I have never used an onkyo but I do own the denon 3808.
The 3808 has an option to turn off video scaling, not sure about the 2808.
MY vote is for the denon.
Several of us got the 3808 for $1098 shipped from JR.com. They were quoting the 2808 for $850 I think.
I would give them a call and see if they still have these low prices on the denons.
Jr.com is also an authorized denon dealer so you would still have the factory warranty.
Also, there is someone else who is selling the 3808 really cheap. I forget who, but the company was mentioned on the "official 3808 owners thread" over at AVS.
