I use a Viewsonic VA520. It's decent. I really went mostly for the small size, since I don't do much gaming.
It looks very nice, matching my speakers, case, and Logitech cordless freedom keyboard and optical mouse. Its refresh tops at 75Hz. All I know is that for the crappy video card I use, it's more than enough.
I think it cost close to $500 when I got it last summer. When I get a good video card I'll set it up as a second monitor and use a decent CRT for games.
Anyone who wants to buy me these things would be quite welcome.
