Consider the Viewsonic N4285P (at Costco)
It's a 42" 1080p display that fits your price range. There is a very long discussion thread on this display on the Red Flag Deals website. The thread contains all the usual discussion comparing it to displays from Sharp, Samsung, etc. Of course, value is very subjective and it depends on your requirements, expectations and your wallet. I bought one and love it.
After some tweeking, the HD and regular DVD pictures are terrific and the SD is pretty good too (via a Shaw DCT4612).
