in my eyes, you've gotta get below 25ms pixel response times for fps gaming. the 1800fp, which is otherwise a very, very nice monitor (with a 25ms response time), definitely has trouble keeping up with counter-strike.
the 16ms panels are all 17". they are all based on the same AUO panel - so they don't differ all that much. warranty, connections, OSD, etc.
these panels are all 16ms 17" lcds on the AUO panel:
Planar PX171M
NEC 1760NX
ViewSonic VP171B
Hitachi CML174, CML175
The NEC is cheaper, but it doesn't come with a DVI cable.
They all get excellent reviews.
I only looked for panels with DVI, so there are analog only models that I didn't list here. anyhow, the first three are all available from dell home. The hitachi screens can be found at monitors direct for $459/$469 respectively, with free shipping, and no tax outside CA. also, they come with a 3 year advance replacement warranty for $.01. yesterday there was a $40 off coupon for the CML174 = $419
