I recently got a Viewsonic VP201S:http://shop.monitorsdirect.com/product.asp?sku=2410753
A bit pricey , but it is a 16 ms 20" with 1600x1200 res. By far the best looking/gaming LCD I have ever seen, well worth it IMHO.
( One caveat however, pushing that much data thru cheap DVI cables lends itself to picking up noise, first time I plugged it in I had what appeared to be "digital rain" all over my screen, swapped on a somewhat more robust DVI cable and the rain lessened, went out and bought a highend video DVI cable and it went away. The analog cable picks up no noise, so you can simply use it analog... still great picture...)
