Oh and spend some time in the stores looking at the tvs. I would use a budget tv in an extra room or bedroom, but I firmly believe that you should have a high-quality tv in your main living room. Derek's Vizio problem is that it's a Vizio...
Also, I would avoid Sony tvs like the plague. Their reliability has sucked for decades ever since North American models were no longer produced in Japan, and they're overpriced relative to other leading brands like Sharp, Mitsubishi and Samsung.
