I'm looking to replace my 7 year old panasonic 50" plasma. It still works fine but I want a bigger screen. My price range is upto $1300. I've seen alot in the price range but is one better than the other. The Vizio M601d-A3R looks really nice. As does the a Sony KDL-60R550A. There are many more but these are the standouts for me. Any others I should look at?
