We are planning on a new home theater setup in our new house and I am currently researching components. My father (the one who is buying everything) doesn't want to spend a huge amount of money and I am looking for a receiver in the $500-$600 range. ecost.com has refurbished denon 3803's and 1083p's for sale, with only a $50 dollar difference. As I have not been able to find any reviews on the 1083p, I don't know what advantages it would have. Which one would be a better buy? Also, are there any other receivers in that price range that I could get that would rival these two?
