I have a WD52528 which is basiclly the same set. In two years I had the Store, where I bought it and in warranty, replace the light engin and mirror. Less than another year I replace the lamp, that one was my cost. What I see is if this set is not in a VERY CLEAN enviroment, you will have problems with things like dust, cooking, etc. It will become a very expensive set to maintain and keep the origional picture quality that you start with. I fyou buy it get a life time warranty!Buy Mitsubishi WD-57733 57-Inch 1080p DLP HDTV!
