I have a Vizio 32" and i LOVE it. Best money i ever spent. My next purchase is the 50". Just goto walmart or whoever sells it and watch 2 tv's side by side.
I purchased a 32in Vizio from costco. The thing had 4 lines running from the bottom to the top of the screen. I ended up returning it and buying a panasonic. The TV does have a great picture and their prices are great...too bad mine was a lemon. You get what you pay for I guess.
