Summary: If you buy this series of projector from Optoma (or any Optoma projector for that matter based on my internet search of similar projector problems), you must be aware of the problems listed in the reviews posted here.
Summary: I bought this projector and scaler back in March 2007. I had it just over 3 months when it developed a problem. It was coming up with a lamp error although it was still putting out light. Even though Optoma originally told me that it was a lamp problem, it was not.
