Funny you should mention this TV. Its exactly what I'm using in my current cab (just completing it) It works acceptably, but does some times shut itself down right after I turn it on, requiring me to unplug it for a few seconds to reset it. The screen goes blurry a few seconds after you turn it on, almost like its syncing up with the video signal. Its during this time that it sometimes shuts itself off. I have no idea why.
The picture quality is good, IMO and I have no other problems with it. Overall, I really can't complain. I got mine as a display model from BB for $124.
