Well for my money, I've already bought one of these:Sharp XR-10X
For the price it is awesome. DVDs look perfect. It will accept many different HD signals, but I don't have an HD receiver yet to test that. It is also XGA (1024x768) native resolution and DLP with high lumen output. Plus the warranty from Sharp is pretty good (3 years with 2 years express care.)
Check it out!
