I basically agree that most extended warranties are not worth buying. Most people NEVER use them and as such, they are "free" money aka "high profit" for the seller.
Having said that, some extended warranties are worth purchasing. I would recommend them for laptop computers. Big screens are also another one, but that is somewhat conditional. How long the warranty is, who performs the service, what you're recourse is if the unit can't be repaired correctly, has repeated problems of if the repair can't be done on a timely basis, etc... Since these devices DO go out of alignment from movement, vibration, etc... having it cleaned and calibrated once in a while can be a good thing. This is not to mention that if you are the poor soul that buys that "lemon", you'll be covered.
My sister bought a large Pioneer tv and it gave her nothing but headaches. Luckily, the extended warranty saved her as she had some very expensive modules go out after the factory warranty. This happened to her twice, so the warranty more than paid for itself.
I did buy the extended warranty on my Mitsu big screen. Although i have confidence that it is a well built product, i had very little to loose. The dealer that sold it to me offers a 75% store credit if you never take advantage of the warranty. As such, it will either pay for itself if i do have to use it or it will have cost me VERY few pennies per day for complete piece of mind. Given the fact that i like to shake the entire house when watching sci-fi movies, i'm sure that it could use re-aligment as we speak : ) Sean
