My BIL is a super tech geek.....and I mean in a big way. Chats on forums and everything (wink, wink)....
He's owned everything from DLP, LCD, Projectors, and Plasma. Says Plasmas now are by far offering the best picture, particularly with "black levels" or some chit I can't remember him tellin' me.
Anyway, I went with a 52" LG 1080p Plasma from Costco for like $899....and haven't regretted that decision whatsoever. Great set, and no burn in issues. I was concerned as well due to the initial problems, but as some here have said, burn-ins on Plasmas have been fixed for a couple years now.
