For the record I have a 50 inch Pioneer Elite. They are no longer being made which is too bad because they have simply the best PQ period. My wife, who is not a big A/V person, actually went to pick it out at BB. She was first drawn to the Sony Bravia, but after seeing the Pioneer she actually called an said it was the only one she would buy, it was that much better. The Panny are good TVs. I have a 10 year old 47 inch RPTV in the basement. It has never had a problem. Good luck in your search.
Lastly whatever you buy have it professionally calibrated. It cost a little money, about $300-400, but it is worth every penny. Also the comment on the cables is dead on. The big expensive HDMI cables are not worth the extra cost. Just buy some good quality cable for a reasonable price and you will be very happy.
Mine is the 62” Pioneer Elite which we got in 1996. We have been really happy with it.
