I got my Dell 2005FPW monitor for $383 shipped. This monitor uses the same LCD panel as Apple monitors and except for the color, would fit all your specs. It's great for gaming, movies, etc.
You need to know how to play the Dell game to get that price, but it wasn't hard. I had to wait about 3 weeks to see the price/coupon deals fall in line to get it but I got it and many others have done so as well. I gave up my beloved RadiusView 21" CRT for this monitor and haven't looked back since.
