Take a look at the Westinghouse 42w2. It is outstanding for the price with 1080p resolution and 3 or 5 1080p-capable inputs. When compared to the other LCDs there, you won't believe they are able to keep this priced so low. They sell it at BestBuy if you want to take a look at it first hand. Usually sells there for $1999.

Keep in mind, the bigger you get, the farther back you need to be able to sit in order to avoid the "screen-door" effect.
