I have a 50" Samsung DLP set too. Replaced the lamp once a few years ago and it has been fine. Picture is still very good IMO. I am thinking of replacing it though since prices are so low right now. Looking at one of the the Samsung LED Smart TVs. I can get one in 55" for $1250. Panasonic has a 55" Plasma I can get for $750 though so I'm kind of thinking of getting that instead.
