Wow, now that was a bump in what you are willing to spend!
Seriously, LCD's are about 12-18 months away from rivaling CRT's for responsiveness and color accuracy... on the other hand, you absolutely can't beat them for a 2D windows environment, and there are quite a few
damn fine 18" LCD's for around $1000.
The Samsung 181T is extremely popular right now... the Samsung 171P is also getting good press, but doesn't look like it will be very available for at least another month or two.
Dell has some nice offerings, 1900FP is a Samsung made 19" LCD for around $1000 with coupons. 2000FP is a favorite with gamers... 25 ms response times, 16X12 (4:3 aspect) resolution and good contrast. I thought about that one long and hard but thought it made more sense to spend $900 now and spend another $900 a year and a half from now when FFD technology brings LCD's more on par with CRT's.
Sony doesn't have any competitive offerings for a gamer (IMHO).
Viewsonic's higher end panels are mostly MVA, which do have better color accuracy but I have seen 3 of them running games and was completely un-impressed.
I ended up ordering an NEC 1850X. Got it for slightly over $900 with free shipping. Respectable specifications, reported to be good at gaming. Best thing for me is that the NEC's have the option of not scaling up the lower resolutions to fit the entire panel (you have the option of displaying the lower resolution image either scaled up but in the correct aspect ratio or just keeping it in a box inside the panel to run it at the real 1:1 pixel resolution). To me that's a big deal... I don't like the stretching that occurs when you run a 4:3 image (like older lower rez games) at 5:4. Nearly all of the other panels are lacking this feature. There is a newer version of this panel coming in a month or two with a thinner bezel, higher contrast and lower power consumption... other specs look pretty similar... it will be retailing for around $1200 initially. The 1850X originally retailed at $1599.
Whatever you decide on, do a
lot of research and make sure you buy from a retailer with a very liberal return policy. You don't want to be stuck with a panel that has a bunch of bad pixels, or one that you aren't happy with.
