For the price plasma is your better bet. You can get a kick ass 50" Panasonic. For example:

Edit: btw, the 800U is one of the best plasmas on the market and one of the highest rated 50" TV's.
Opposed to a nice 46" Sharp LCD that is more money and doesn't have a better picture (unless you watch a lot of cartoons...then the artificially bright colors will look nice.)
