I will let others comment, but do yourself a huge favor and consider a plasma. LCD, even with LED non-edge lighting, is an inferior technology to plasma. Unless you are in a bright room, concerned about heat (not a big issue), or power usage (also not that big of deal anymore), get plasma. Also, anyone who mentions burn-in has not looked at a plasma since 2004-05. Doesn't matter anymore, unless you put the espn logo dead center for 100+ consecutive hours.
Once you look at plasma, go panasonic first, and samsung second. In my experience, (haven't looked at this year's models) LG's a cheaply made and lack quality processing. A $1200 Panasonic plasma will blow out a $2000 Sony LCD (except in the instances listed above).
This may sound pompous, but do some independent research and you will likely agree. Note I said likely.
