Buy LED, LCD or Plasma

My current two favorites are the Toshiba 670U series (comes in 46 and 55 inchers) or the Sony XBR's.

I have all three - my preference is Plasma - assuming picture quality is your goal.

esp. if your room is dark and/or you'll be viewing at an angle, generally speaking plasma still does look better. panasonic or samsung--look at dealmac or bradsdeals to find the best online deals on a daily basis

Plasma.

Plasma has the most natural picture and best viewing angle. Although viewing location is not quite as critial as speaker placement, you may consider placment in front of the fireplace using the table stand. Above the fireplace installs look nice when the television is not being viewed with programing but the best TV viewing location is close to eye level. That being said, if you do consider my suggestion, the new LED backlit LCD's are extremely light in weight and can easily be moved by one person if a fire was desired on a cold winter night.
