I currently use a Pioneer 503MXE plasma screen and want to add a projector and motorised screen. I have recently completed the audio side of my system with a set of B&W Nautilus 800s. Audio has always been more important to me than video, so I don't know much about projectors. As you can tell from the title, the Marantz DLP is currently top of my list. I havent actually demoed any yet and am just compiling a shortlist from online research and reviews. I've definitely ruled out CRT due to the problems some members have encountered with support etc. I know that lamps will last an average of 2000 hours are there any other parts that require replacing or maintenance? I know that my plasma will typically last at least ten years, what is the average life expectancy of a projector? Can you recommend a 8' plus white motorised screen?
