My 2x mitsubishi hc3100's and infocus sp7210 disagree. All three projectors had complete color wheel failures at or before 800 hrs. My neighbor's mitsubishi hd1000 made it to approx 2000 hrs before the color began to whine, he's now searching for a replacement.
I've also owned a marantz vp12s4, infocus IN78, and planar 7130. My current projector is an Infocus IN82 and I'm closing in on 6000 hrs... the color wheel seems to be holding up fine. I don't care for lcd or lcos, hence my persistence with dlp projectors.
I don't know how you can say "dlp does not have a specific issue relating to reliability" when color wheel's are spinning upwards of 10000 rpm. They're ticking time bombs from my experience, even if they're using quality brushless motors.
