well I can say ive had my z3 just under 3 years, and though i hear about issues with honoring warrantys for some, i had no issues. I sent my unit in 2 times, first time about 7 months ago i had a blue polarizer replaced, then last week it was really looking bad, sent it in again, they replaced the lcd panel inside, now it looks brand new, no questions when the unit was in, both times I sent the unit in on Monday, had it back on Friday. However, epson has a overnight replacement program that sounds amazing, so my next unit will most likely be an Epson
