First picked up one of these for $329.99
Next grabbed one of these for $49.99
Then to the beer store for some inspiration and spending some time getting it calibrated.
Man this is just kick ASS !
It's one kick ass monitor and might be hard to find to in the US try Circuit City but otherwise I can't recommend this one enough. 20.5" is more than enough to game in and you don't have to be right up close to it.
