While all of this tech talk is completely over my head, I have been doing a little research for my own purchase. I think I am sold on this Vizio:
It can be bought at Costco for $600 - $700. The CNet review isn't the best that I've read, but the customer reviews are a lot better. I think this is one of the best "values" in HDTVs right now. I'll be using this as a secondary bedroom TV.
