The Home Cinema 5010, and the 5010e come with a two year parts and labor warranty, which in this price range is typical in length. There are a couple of one year warranties, and even a couple offer three years. What sets the Epsons apart is their replacement program.
Both Epson models also come with a replacement program for both years of the warranty. A couple of other companies in the price range offer a one year replacement or loaner program, but most offer just basic warranties.
Depending on the time of day you call, your replacement projector might actually arrive the next business day, or the following. You can't beat that.
Epson provides owners with a hotline number. Calls go directly to the tech support folks, typically in under 2 minutes. When I owned Presenting Solutions and was a large online dealer, we always considered Epson's support to be excellent. Nothing I've heard since, would indicate otherwise.
You are going to be hard pressed to find a better warranty on any projector anywhere near its price.
