Figure should you encounter a problem after the warranty runs out, most likely it would be time for a new lamp (or soon), and after 3 more years, no doubt, you'll be able to replace the Pro8200 with something newer and better, for less than the cost of a repair, and a new replacement lamp. Afterall, three years or so, ago, an entry level 1080p home theater projector was still $2000 minimum - twice the price.
Viewsonic also offers a lamp warranty - also a lot better than most - with a 1 year warranty. 90 day or 180 days tend to be the most popular lamp warranties.
With no filters to change, and a great warranty, the overall cost of operation of the Viewsonic Pro8200 should also be nice and affordable (minimal cost).
Taking a quick look at the competition: The other low cost home theater projectors competing against the Viewsonic Pro8200 overall, include the BenQ W1000, W1000+ (1 year warranty), the Optoma HD20 (1 year warranty), Vivitek H1080 (also 1 year warranty).
In the slightly more expensive group: Epson Home Cinema 8350 (two year warranty, with replacement program), Mitsubishi HC4000 (two year warranty).
We cannot think of another under $1300 home theater projector with a 3 year warranty, so chalk up a big plus for Viewsonic's Pro8200 warranty program!
