1080p Home Theater Projectors: Warranties
First some commentary - I do not believe that a 1 year warranty on a 1080p projector qualifies as a good warranty. Two years, on the other hand, is more typical, and some offer three years. Considering if you have a problem you have to ship the projector, and in general, projector repairs are expensive (you might have to pay $100 - $175, just for an estimate, when your projector is out of warranty). A major problem may easily cost more than $500 and a light engine problem could cost a lot more, out of warranty.

Again, my recommendation, is one way or another, be sure to have at least a two year warranty. I say this despite the fact that I never buy 3rd party warranties on lower cost electronics, etc. On gear this expensive, and expensive to fix, though, you could find yourself with a "throw-away" in the second year, if the warranty has run out, and the repair is major.
Lamp life warranties, are typically 90 days, although a couple are 180 days, and Optoma, provides a 1 year warranty, most unusual (but nice).
Those same 3rd party warranty companies also sell lamp warranties. If you are a heavy user (40 hours a week, or more), you might want to consider those (they are fairly inexpensive). Be sure to read the fine print.
Lastly, with several of the projectors in this report there have been various problems reported. Some Epson "UB" projectors have slight convergence problems, the Sony VW40 has some reports (including our review projector), of blue hotspots in some of the corners (you should only see them on the darkest of dark scenes, if then), and so on. Color shifts in the background are another reported issue on occasion, with many models. Just in this group of 16 projectors that were physicall reviewed, four, including an Optoma, a Panasonic, and two others had some color shifting in the background that is more than normal. Of the four, two were pre-production units.
All considered though, home theater projectors tend to have very good quality control, and are very reliable.
Interestingly, the story with the Epson projector's convergence became significant when one dealer of the Pro version announced on their forum, that they were QC'ing the projectors before shipping to customers, and had a 50%+ rejection rate. That dealer told me he had gone through about 70 projectors, and rejected more than half.
To me, that sounded incredible (especially since I have long felt that Epson is about the best there is in overall reliability of the big name manufacturers). For that reason, I polled five medium to huge online projector dealers, that happen to advertise on our site. Each responded to me, and when I added them all up (I asked for the percentage returned because of that issue, and their approximate sales of the Epson Home Cinema 1080 UB), the final combined sales numbers was at least 400 (probably much closer to 500) projectors sold, was less than 3% returned for convergence problems, as of today 3/14. Go figure! We are all trying to sort it out, to figure out why one smaller dealer has three times more "unacceptable" projectors, than five larger dealers combined.
This is another reason why a replacement warranty is such a wonderful thing. In following these issues in the online forums, Epson for example is immediately shipping out at their expense, replacement units (and also paying freight to get the problem ones back). These come from their "fleet" of refurbished projectors, but most people seem very pleased with Epson's support. I haven't any details on the scope of the Sony issue, or how they are handling, since they don't have a replacement warranty.
