Help choosing a new monitor

Hey, im thinking about choosing a new monitor to replace my 17" MAG innovision CRT with a good LCD. I use it to browse the web however most of the time its to play games. I want a good 20"+ LCD, with VERY good quality, however my budget only allows about 250 USD.

Any suggestions would be nice, my current specs are:

Pentium D 925 3ghz dual-core
Asus x1950pro 256MB video card
2GB patriot 800 ram

Stick with a better LCD manufacturer.

And at that price range, you should be looking for a 20" LCD.

I recommend the Samsung 206BW, or the LG L206WTY. Both have great response times, decent contrast ratios, and are readily available at that price point.
