I purchased this at Best Buy last week. I was expecting to pay $599 which it is listed for online. The price at the store was $499. I am happy with the picture except for one thing. light bleeds into the upper left and right corners when the screen is black. Typically this is only noticed when I am watching a letterboxed movie. I have contacted Westinghouse. They have instructed me to call a special customer service number. Otherwise the picture is great. When watching regular HD TV the picture takes up the entire screen, so I do not notice the light bleeding. Maybe this is a common problem with all LED edge lit TVs.
Also, Best Buy lists this TV as 120 hz. I am not certain that it is. The Westinghouse website does not include this spec. The 39" version is only 60hz. The reason why I suspect the 46" is only 60 hz is because when I change the channel, the tv displays the type of signal and the hz in the upper right corner. The only hz number I have seen displayed is 60. Still I have watched some sports and the picture is good enough.
