Please allow me one more opportunity to agree that Brandsmart is the closest thing to Hell on Earth. AVOID.
There is no doubt that Vizio TVs give you the most for your money, and the quality is good too. There isn't anything wrong with them. Personally I like Samsung TVs, which seem to have better prices than they once did since Vizio has been around.
I'm going to have to disagree based on my experience with Vizio HDTVs. My inlaws have a 42" set that they had for about a year when a dark black cloud appeared over the right half of the picture and quickly spread. No warranty support and they bought it from WalMart, so they were SOL.
I myself bought two 20" Vizio HDTVs (in succession) for use in the bedroom. Both units had defective speakers. One would buzz loudly when the mute button was activated or the volume was turned all the way down. Did some poking around the AVS Forums and discovered it was a known issue. The next, which was a slightly newer model that supposedly fixed the problem, buzzed while the volume was up. At that point I gave up.
There are many things that can go wrong with an HDTV, and you essentially get what you pay for. I also am a fan of Samsung, and have one of their 32" LCD HDTVs in my living room (top-of-the-line at the time), but after three years in service, it's started to show some faint clouding/burn-in on the upper right-hand side as well. So who knows. Hoping to upgrade to a 40" (the biggest my cabinet will allow) Samsung LED backlit LCD soon.
