I just ordered an AVR-4310CI for a super good price and from an authorized dealer, so I thought I would share.
I searched through
Bing Shopping (I registered for cashback quite a while ago) and I ordered from Electronics Expo (seventh down on the search page) for $1293 with free shipping, a huge coupon code discount, and Bing Cashback. Their site looks nice but it is slow and the add to cart button adds 2 quantity so you have to fix that before you check out, but they are listed on Denon's site as an authorized dealer, and their reseller ratings aren't too bad.
