Not sure if you've made a purchase yet, but wanted to make sure you knew about Shoponkyo.com. Sometimes they have different refurb models then accessories4less, and if you catch shoponkyo with a 10% off refurbs which they run quite often you can land a great deal.
I have an 805 myself and am vastly pleased with it, but now that the tx-nr807 is out I may need to do some thinking about swapping out. Still need to find some reviews on the amp section on the new models to see how they compare.
