I have to put the good word in on the Cornerstone brand monitors. I purchased their 21" monitor (the p1701) and I have a 5 year on-site replacement warranty with it. It's the clearest, sharpest monitor I've used. It supports extremely high resolutions and extremely high refresh rates. Look into it. http://shop.monitorsdirect.com/product.asp?sku=1088405

You can run 1856x1392 @ 85Hz, 2048x1536 @ 80Hz. It's really quite a sweet monitor. The latest iteration of it is 22". But you can get one of these for $600. That's cheap!
