My issue with a lot of the new tvs, particularly those at Costco, are the side viewing angles. We have a 25x25 ft room. I don't want to screw the people who aren't directly in front of it.
I like this site for reviews and this is one that looks like it'd fit my needs:

If you have further suggestions, by all means I'd like to hear them.
