The Optoma HD81-LV Projector Review - Warranty
Optoma offers one of the best warranties in the industry on the HD81-LV. Their 3 year parts/labor warranty offers their Express Replacement service option. Only a few of other sub-$10,000 projectors offer three years, and, if I recall correctly, only Epson, on their Pro Cinema 1080p, offers three years of replacement program.
It would seem the replacement aspect covers the projector itself, and if I am reading things correctly, the processor box has a separate 3 year warranty, but no mention of an overnight (or express) replacement.

According to the Optoma website, the lamp comes with a 1 year warranty, which is far longer than the usual 90 days most manufacturers provide, (although there a few projectors with 120 day, and even 6 months coverage). The site does not mention any limit on the number of hours on the lamp.
Let me summarize! It looks like this is the best warranty in the industry, at least in the sub-$10,000 range, with perhaps one, or two other projectors offering similar coverage, but most have either 1 year or 2 year coverage, and most don't offer replacement programs.
Tough to beat!
