If your looking for a great LCD for cheap, check out Dell (this should be the only time I EVER endorse such a company). I have their 2001FP which is a 20.1" LCD (Inputs: DVI, VGA, S-Video, and Composite. Has an upstream USB port on it for hooking into a computer and then four downstream ports on the side of the screen, all USB 2.0 which is pretty sweet. Oh, and you cannot forget a 16ms response time...pretty sweet on a 20")
My friend already has one and just ordered a second for the great low price of 645.cc USD, which is a pretty hot deal. If it matters to you, like it did to me, LG makes the panels for Dell in their 2001FP monitors. They also have a new 2005FP which is a widescreen version if you prefer that, but it is actually less physical realestate, depends on what you prefer. I love mine, works great, not a single dead stuck or hot pixel, awesome when you flip it tall for word or browsing, and just overall a pretty nice product.
There you go, thats my vote. I am not sure if my friend had some crazy coupon stacking or not, but with Xmas and the like, you should be able to pay no more than 700USD, probably less
