So far, working with Crutchfield is a plus. I now have a comparably priced and featured Sharp AQUOS 42D64U swap on the way from Crutchfield and they are taking the Panasonic back. Can't complain about service like that!
I did like the picture and the sound quality of the Panasonic, but I found too many references on the 'net about Panasonics quitting exactly the way mine did. Couldnt bring myself to try another one of them.
Now -- if the AQUOS gets here by Super Bowl Sunday -----
