Samsung 181T or 191T hands down. It's a great all around monitor, is actually one of the best for pixel response time (this does matter even outside gaming for things like scrolling pages, etc...), and size. Also, if your video card supports it, the stand rotates for a portrait view. I have a hotkey sequence that I can press to rotate the display.

Standard warranty on these is 3 years, and a 2 day FedEX cross ship option direct from Samsung.
