"Make sure to get one with 1080P and not 720P."

720p vs. 1080p or How to Save Money With a Tape Measure
Here's the thing about whether or not you need to blow the bucks on 1080p—it depends on your big your TV is, and how far away you're sitting. Under 40 inches you usually cannot tell the difference unless your nose is pressed up against the glass, and your mama told you never to do that. Bigger than that, it depends on how far away you're sitting. The average viewing distance from a TV in an American home is nine feet. At that distance, it takes at least a 46-inch TV to see all the details of a 720p picture. For a 1080p set, you would need a 70-inch set! If you buy a 42-inch 1080p set, you should place it within six feet to make the most of it, seven feet for a 50-inch 1080p set. If you measure your living room and the distance is much greater, you should seriously consider buying the last of the 720p sets available at serious cheapness. Lest you think we're making all this up,HD Guru's got a PDF chart with distances and the right TV size for each resolution.
