I'm totally satisfied with my 17" Cornea monitor. It's got inputs for VGA, DVI, S-Video, and Composite Video, plus a built-in TV Tuner! So you could conceivably hook up your computer to it with VGA or DVI, your DVD player or Video camera to it with S-Video, your Playstation to it with Composite Video, and your cable box to the TV Tuner (coaxial cable). Here's a link to the product at J&R:

I bought it for $650 about two months ago, but as you can see its price has already dropped to $600 (and I've seen it for even less at other sites). It was the best value I saw for a 17" monitor two months ago, and it's an even better deal now. The DVI connection is key, since you want to make sure your purchase is an investment in the future, and the cheapo 17" monitors that are selling for $500 only have a VGA connection.
