I second Buckeye's motion earlier.

Ubid has some great receiver models, they are usually auctioning around 30 receivers at any given time. I believe the model Buck was referring to was the onkyo 602, which is currently being auctioned to the highest bidder with no minimum payment. Definitely something to check out.
Also, Ubid is an authorized dealer, so no worries about not getting the warranty unless ubid SPECIFICALLY says so, which I have yet to see happen.
