I am looking at 4 sets and would like opinions. I have gotten very confused while studying which to buy. All 4 are in my price range and vary from $1600.00 to $2000.00. Hitachi 51S715 Mitsubishi WS-55315 Sony KP-51WS520 Panasonic PT-53X54 They also have Hitachi 46F500 that is discounted. My room has 2 skylights that let in a lot of light. How much will this effect the picture and is one set better than another. Which of these tvs will give me the best picture quality. I have satellite and my watching habits are 15% dvd-40% sports and the rest is standard programing. Which one converts standard defination programing the best. All opinions will be appreciated.
