I can't say much about a refurbished unit but a friend of mine just picked up a demo Denon 3802 and i have to say, i'm very impressed.
The US equivalent cost would be about $930. You might want to consider trying to find some demo models or the remains of last year's models while they are now on sale and being pushed out for the newer items.
Call around.
