My 60" Mitsubishi is 11 years old and finally starting to fail on me. I'd rather get a new TV than fix this one because the picture quality on an old projector just doesn't compare to new 720p and 1080p. So, I'm looking for something 50" or larger, and under $1,500 preferably. Picture quality is very important, as is the life of the product. Should I go with Plasma or LCD? Specific brands better than others? Specific features I should be looking for?
