I never go with extended warranties and have been fortunate enough not to need them, years ago I dropped an old receiver and sent it to Denon to get it fixed and they charged me less than $50.00, I think it cost more to ship it.
Imo it would be cheaper to go without the extended warranty if you have a good service center near by. In my case I've never had any problems with well made electronics.

A computer once beat me at chess, but it was no match for me at kick boxing.
