Optoma HD65 Projector Warranty
The Optoma HD65 comes with a basic one year parts and labor warranty. While 1 year warranties are not uncommon on the 720p projectors, just be aware than many competitors do offer more. Most notably Epson's Home Cinema 720 not only comes with a 2 year warranty, but provides free (they pay all shipping) replacement if it fails under warranty. Panasonic's popular PT-AX200U however, also only has a 1 year parts and labor warranty.
Unless you plan to keep your projector for only a year, I recommend an extended warranty so you have at least two years total. Mind you, I'm not normally a fan of extended warranties, and almost never buy them myself, but one year warranties seem short to me, for an expensive piece of gear. My logic is, if it breaks during the 3rd year, you can probably replace it with something better for less than the cost of the repair. But if a projector fails you in month 13, and you have no warranty, you are definitely not going to be happy! The good news is that the extended warranties are pretty inexpensive.
