Costco has a 55" Akai RP widescreen for $1599, I believe. Picture looked great with the HD signal they were piping in. Sound was also very good from the onboard speakers. The cabinet wasn't the most beautiful I've seen, but at $1600 that is alot of bang for the buck. Whatever you do don't break the bank this time around - whatever you buy will be totally obsolete in a few years, regardless of the price tag that it carries today.
I love my Phillips 60" HD (also available at Costco for $1499), especially for sports.
