Lamp Issue >90 Days? Yes
Lamp End-of-Life: January, 2010 (exploded; loud pop) - 8 monthsLamp Hours: ~350
Resolution: Epson overnighted replacement bulb, free of charge
Clearly there's either a problem with their parts (lamp) supplier, or there's a defect in their projector design. I explicitly asked the Epson CSR about this and they said they were still uncertain what the root cause was (which is ridiculous in my opinion, since the issue has been going on since day one for 8100 owners).
As is, I would NOT buy an 8100 because of this uncertainty of lamp life and the insanely high cost of replacement lamps.
However, I must give credit where credit is due- Other than the lamp life issue, I love the projector. Image quality is superb, it's extremely quiet, controls are great, lens is sharp, and the customer support is excellent (low wait time, easy to communicate with, polite, and exceeded my expectations on issue resolution - no 'escalation' to tier 2/management, overnight delivery)
For complete resolution, I would like
Epson to say:
Yes, we found the issue. It was with quality control of part X and we've fixed it. Anyone who continues to have issues with part X will have it replaced with the new part/lamp/projector, and we warranty it for x hours of lamp life.
Only at that time I would recommend this product - and Epson - 100%.
