I have arrived to get your thread back on track

I switched from DLP to LCD and will never go back. I ranted some time ago that I had a Sharp DT100 DLP that died (colorwheel issues) after about 2600 hours. It was good up until that point and you couldn't see much rainbow effect. I then used an Optima H77 DLP that died after 2 hours, then its replacement died after about 200 hours, and then its replacement died after 100 hours, plus the rainbow effect on it was almost always noticeable and annoying. I also saw a Sim2 fail right before my eyes while I was shopping for a receiver. I am pretty sure DLPs have more mechanical things inside that can fail when compared to LCDs.
My first LCD projector experience was with the Sony VPL-HS60. I have one and installed one at my dad's. Screendoor effect was rarely noticable. Mine is at 1400 hours and he just upgraded to a Panasonic PT-AE3000U after 2700 hours and we never had a single problem. Unfortunately, the black levels on the Sonys were not quite as good as the Optima DLP. However, I demoed some LCoS, DLP and LCD projectors at 1080p when we were shopping for the Panny, and determined that the black level issues were gone for the newer projectors. After demoing Panasonic, Epson, Sony, JVC, Sharp, and many others, we determined that there was no contest for bang-for-the-buck features and picture quality for the PT-AE3000U. At a slightly higher cost, the Epson PowerLite 1080UB was a close second, and its new model, the 6500UB, may or may not trump the PT-AE3000U in terms of features or PQ - I haven't seen one in action. We couldn't be happier with the Panny

Anyway, I originally had a original slight priority of reliability over picture quality. I think you can now get the best of both worlds with an LCD. Additionally, if you are in the market, Epson's warranty can't be beat: overnight replacement for 2 years, and Panasonic is still offering a free extra year with the AE-3000U if I'm not mistaken, though it isn't quite as good as a replacement warranty.
I have also heard good things about the Mitsubishi PJs, but have no direct experience with them.
