I got this bad boy a while back. It is 480 mHz for about the same price, and has all the other shite as the one you are looking.
Some people look down their nose at Vizio b/c they entered the market with a low-price strategy to gain market share, and b/c they are sold at Sams/Walmart.
That is not the case with this company now. I can tell you, everyone who sees my TV is stunned.
I am getting the 3D glasses for xmas. I get 5 channels on DTV in 3D, and have heard it will be very cool, but can't comment on that aspect at this point.
