Tanglin,
I saw the same prices you did and decided that the warranty was important. I don't want to be stuck with a $599 doorstop six months from now if there is a major problem.
Keep in mind that even on the HTR line, there are only a few authorized internet dealers listed by Yamaha. I got mine from jr.com. Can't tell you if I am happy yet, because it just arrived today.
But, after reading this thread I am sure I will be. I'm even more confident after reading between the lines of the new article on the front page "Product Managing Receiver Platforms" by a former Yamaha product manager--Same electronics, different packaging and distribution channel, minor feature diff's add up to the ability to get a lot more bang for the buck in the mass market channel in Yamaha's case. But that is not always the situation....look at the deal Nomo was able to get locally for a little more than I paid!
Let us hear what you decide!
Mike
