So my oh so generous older sister asked me what I want for Christmas. I would like a flatscreen HD TV to be played on my 360. I don't want something that's too big or too small, its probobly going to be mounted on the wall of my bedroom. I heard the best bet is using a HD computer monitor and using some with DVI inputs, but I'm not sure if that's the best. Also it can't be too expensive, seeong as how it is a present from my sister (who just recently got married, is having a kid soon, and has a house of her own. So any reasonably sized, light, good quality, cheap HDTV's out there?

A 22" Computer monitor would fit your description pretty well.
