Mitsubishi's warranty on the HC6500 is, basically an industry average warranty for 1080p projectors - 2 years parts and labor.
By comparison, Sanyo offers three years, with a rapid turn-around program that promises Sanyo won't keep your projector more than 3 days, before shipping it back. Epson, like Mitsubishi, offers two years, but also includes its overnight replacement program, a real plus. Panasonic, looks to be sticking with its one year warranty, on their PT-AE3000projector. BenQ offers a three year, with first year replacement program (two day), on their competing W5000, and InFocus provides a two year warranty on both their X10, and IN81projectors!
