I am going to buy and hook up a receiver at this guys house and he wants me to hook up his 7.1 system along with 3 other zones in his house. What receiver should I get for him that would handle the 7.1 and 3 other zones? He wants to spend under $1000 for the receiver. I've looked into some models but some of the models want you to use the the remainder speaker inputs for the 7.1 for the multizone. I need to keep the 7.1 there and have 3 more zones available. Any ideas? Thanks -Greg
