50" Plasam Screen Folks, I am hoping that sometime in the next year I can take the really big plunge and get a 50" PS. I was in NYC yesterday and stopped at the Sony Center and saw their best stuff and the 50" looks good and sleek and with an HD signal it is awesome. I then went down to Sound by Singer and looked at the Runco's 50" (which I had seen before). First to my surprise the list on the Runco was only a few thousand more than the Sony. The Sony comes with a standard TV tuner (but they are cheap). Second and most important the Runco comes with a scalar that gobbles up everything else out there. Third, we are talking serious money here, does anyone have experience with either Sony, Runco or any other PS's.
