Go to any electronics store like AA Electronics, or RTC, there buzzers are like $1, they have a wide selection of electronics parts as well for cheap, no rip offs like radioshack.

meh piezo buzzer from radioshack is like 4-5 bucks, the exact one used in the article is all you need anyways. I guess if its more convenient then hit one of those electronic shops, but I'm closer to a radioshack lol
