I want to upgrade from a 32" JVC that's 8 years old. I want to get a 50" RPTV. I watch allot of analog cable, but I'm about to get DirecTV. I also watch allot of DVDs. Whats the best HD RPTV for me? I've seen the Sammy 43" DLP and was blown away by the PQ, but It was playing a HD feed and I was not able to watch SD on it. I also saw the Sony 50" GW and thought the PQ was very very good, but not as good as the Sammy. I was able to watch on the Sony and thought it was good considering the horror stories regarding SD on HD I'd heard. How bad Is sd on the Sammy. Considering my viewing habits and a VD of 7 feet, whats the best choice?
