plasma is for bigger screens, lcd's usually for 20-40".
lcds are the best bang for the buck imo, it's physically lighter, colours are brighter and generally higher contrast, and immune to burn in (from sports tickers, video game health bars etc)
plasmas are heavy, but u can view the picture at greater angles, i heard they never lag at showing fast moving video/feed and that lcd's can sometimes do. don't quote me on that.
as for brands, i'd go for samsung.

I have a plasma and an LCd and the plasma blows the lcd away. The rear projection lcd's are worse IMO, but they can be had for a decent price for a fairly large screen. I'd rather have a small, better quality one though.

if u have a window that produces glare on your current tv you might wanna take care of that first with maybe some heavy fabric drapes or california blinds etc
rear projection lcd sets look great in a dark room cuz thats when the rich and deep black come out and the colours pop...dlp projection screens are also something to look at
people will always say this and that but in the end its what works best for you in your house...goto a home theatre shop, get advice from them...but dont buy from them, go elsewhere and get a better deal

I just find the colour much more vivid on my plasma. Also, the response time on the lcd lags compared to the plasma.
I've had my plasma for since last October I think and it has been problem free. Sure they have a lifespan, but mine is something like 60000 hours. That is ALOT of viewing. I play Xbox on it regularly with no burn in. Most of the rumours about plasmas are just that.
I like plasma better, but thats just my opinion. Go see a few different ones in person and decide for yourself.
Here is some good reading.

plasmas win when in a lit environment
lcds win in a dark environment
plasmas are great for sports and action movies
lcds are great for animation, general tv programming and are acceptable for sports etc alot of the newer sets are pretty fast but there maybe some relics and action trails in some cases
my buddy's plasma main board went on him in less than a year...it was covered under warranty but he was without a set for 8 weeks...but things like that can happen with anything

Generally, LCD will have twice the life span over Plasma.
Plasma have larger screen size availability, better contrast ratio and the ability to render deeper blacks, better color accuracy and saturation. However, Plasma TVs are more susceptible to burn-in of static images and have a shorter life span (about 30,000 hours or 8 hrs of viewing a day for 9 years) than LCD (60, 000 hours).
LCD don't get burn-in but can get dead pixels which is when an individual pixel on the screen burns out causing that pixel to be white or black. LCD can have lag for fast motion but the current standards are 6 - 8 ms of lag time which is better than 20 ms from some of the older models.
If you go with LCD, I'd reccomand the Sharp Aquos line, pretty much the top dog by many.
Also if you plan on picking up a PS3 and other goodies that have a HDMI output make sure you get a TV that has more than one HMDI on the back.
Best of luck.

I just got a 42 inch LG plasma hdtv, but I'm wondering about this burn-in issue. Has anyone actually experienced this problem? Also, how long does one image have to be on the screen for this "burn-in" to occur?
thanks in advance for any help

(1) Some obvious advice: Do not leave static images on your plasma TV screen for more than an hour. Turn off your unit when you are not watching it. Do not pause DVDs for more than 20 minutes at a time.
(2) Know that plasma screens are more prone to burn-in during their first 200 hours of use. When phosphors are fresh, they burn more intensely as they are ignited. This means that relatively new plasma display TVs are prone to "ghosting", which occurs when on-screen images appear to stay on the screen belatedly. This is a function of the high intensity with which new phosphors "pop," and this phenomenon usually "washes out" on its own, as the screen displays subsequent images. Displaying a bright, or moving snow image (as with a DVD or VCR with no input) will "wash" a ghost image from the screen in most cases. Many plasma manufacturers have installed anti-burn settings, which are monotone gray or snow screen settings which recalibrate pixel intensity levels uniformly - thus eliminating any image retention (ghosting). It is a good idea to run this type of program after the first 100 hours or so.
(3) Adjust the CONTRAST setting at or below 50% on your new plasma TV. These days most plasma TVs are preset to either peak or very high contrast (also called picture setting on many TVs). This forces phosphors to glow more intensely, which decreases the length of time necessary for burn-in to occur. Our advice is to reduce the contrast setting to 50% or less for the first 200 hours of use. And, be sure to avail yourself of your plasma's anti-burn-in features.
(4) Some plasma televisions burn-in more easily than others. In my experience, AliS type panels -- the ones utilized by Hitachi and Fujistu -- seem more readily given over to problems with burn-in. As well, be more wary of the 2nd and 3rd tier brands as their technology is usually not as up to date as some of the better 1st tier brands.
(5) When displaying video games and other content which have static images, use your burn-in protection features like power management settings, full-time picture shift (both vertical and horizontal), and automatic screen-saver functions. Check your Owner's Manual for further information.
(6) Realize that quality matters with burn-in as with everything else. Purchase a plasma display that has really good scaling, so that you can watch 4:3 TV programs in widescreen comfortably. It is better not to display black bars on your TV screen for prolonged periods of time (especially in the first 200 hours), so you are probably better off watching most everything in "full screen" mode. This should not be much of a problem todays selection of widescreen HDTV and DVDT content.
Also, higher quality TVs tend to be more resistant to burn-in -- though not entirely immune to it. Of the plasma displays I've owned and/or tested extensively, NEC, Sony, Pioneer, and Panasonic seemed least prone to burn-in once the plasma screen was properly broken in.
Note: There are some applications which are simply not well suited to plasma display technology. The static flight schedule signage at airports, for example. It amazes me to walk into an airport and see a ruined plasma display monitor hanging from the ceiling with what is obviously an extreme case of permanent burn- in. As LCD monitors have increased in size, they are being used to replace plasma displays in this types of setting.
The Bottom Line on Burn-In
Plasma TV burn-in is not an issue that should cause undue concern in the average user. With a modicum of caution, most plasma TVs will probably never have a problem with image retention. A viewer may experience temporary ghosting, but this is not cause for alarm.
