It is actually pretty straightforward to set up - the menus are only one screen each and laid out in a logical order for doing a complete setup in one pass. (And no cute but cryptic icons identifying menus, something that I've always found a bit annoying when I run into it on DVD players.) Any surround receiver or processor today is going to be complex to set up, but if you've done it before the 990's a pretty comfortable one to work through. The manual's also goign to help get you through.

I don't know what the market price would be for your Yammy - I'd probably watch Audiogon for a bit and see what others are asking. Perhaps some of the folks around here who have recently upgraded from Yamaha can shed some light on that.
