RSP-1066's can be had for about $1000 now, as the newer 1068 has been released. There's nothing earth shatteringly different about the 1068, so there's some deals to be had if you're willing to take "last years model".

I've seen the RMB-1075 go for about $750 - 800...for for under $2000 you can have really nice separates (if that's your thing). High end receivers cost more than that.
