Denon's seem to be pretty reliable units. The only complaint I ever hear about them is that their manuals are horribly written. I concur.

My personal thought on extended warranties is that if I had taken the ext. warranty every time it was offered to me on something, I would likely be able to have replaced any single item a couple times over with all that cash. I'd prefer to keep all that money in my pocket for my own uses until the day comes I need it.

With great power comes Awesome irresponsibility.
