The Samsung 710 is one of the best 720p projectors. It was costly because it's colors are so accurate, but now Tigerdirect has it on firesale. The colors and shadow detail are supurb. Here is a review and another. Samsung also sends you a repalcement projector in 2 days if it breaks under warranty. The main flaw is it's large size.
Geeks.com has the 50 inch Vizio Plasma Monitor (requires external tuner or cable/satellite) for $970 shipped. A less reputable dealer as it for $40 less. See prices here. Cnet gives it a decent review.
