Get a widescreen LCD man, they're so nice. My mom has this nice 22" and I have a 20.1" and both are a joy to use.
I was thinking about it and I'd really like something capable of HD (1920x1080), but I seem to be in a standstill. I can't find any good CRTs that go that high, and the LCDs that do are definitely out of budget.
This doesn't make sense as even 20" widescreen LCDs run at 1680x1050 which is far better than 720p and nearly as good as 1080p. However, 1080 content will scale down to fit all the pixels your screen can display which will look fantastic all the same. You're going to have to drop a pretty penny to get a 24" widescreen LCD which DOES run at a better resolution than 1080p. Check this
little chart I found on wikipedia if you want to learn more about how resolutions compare.
I would recommend a 22" widescreen LCD as you can get them for $200 on TigerDirect and they really do run at a beautiful resolution. I can't honestly see the need to drop $300 more for 2 extra inches and
true 1080 greatness (you know deep down you want it just for braggin rights anyway).
Make sure if you get an LCD that you get the DVI hookups for them. The quality is worlds better through DVI (DVI is just like HDMI except it cannot be encrypted and does not carry audio).
