Depending on your budget, you can get a basic Dell 19" (E193fp, 1280x1024) for as little as $265 on sale; although it has but an analog input, I'm very happy with it, and I can detect no ghosting during gaming.
Also from Dell, you can find a 2001fp (20.1", 1600x1200) for around $503 every couple of months when Dell has a sale; i bought one in early Jan and love it, arrived in 2 days, free shipping!
