Yeah that's what you want to look for. I think ViewSonic has one with a 2ms response time at an 800:1 contrast ratio. Lemme check the price.
Fastest monitor in the world:
Openbox (more like guaranteed deadpixels):
But it turns out that its a 650:1 ratio. I'm not sure exactly how much the contrast ratio effects the apearance, and you can't exactly go into Circuit City to see them or anything because they just feed all the monitors a crappy signal that makes them all look terrible.
Do you understand response time though?
