Trog, as the owner of a new Dell 2000FP, I can highly recommend that as an option. Even though it's bigger than you're looking for, it's priced right around the same as most good 19" units, and Dell always has sales going on lately w/ free shipping, $100 off, etc., so maybe it's more within reach than you realize.
I use it mostly for FPS gaming...NOLF2, MOHAA, AVP2, also games like High Heat Baseball 2003. I get zero ghosting. Even some of the most frantic levels in MOHAA, where I'm running around like a chicken with no head, it's amazing. My games never looked so good. And, yes, it scales very well...I'm actually playing MOHAA at 1280x1024, and it's incredible. Just something to think about...
BTW, it's connected via DVI (must-have with this unit) to a GF3.
