Something to keep in mind as well Greg:
Before you got yourself into the AV doghouse with the latest speaker purchase
You were considering the RX-V1800. Unlike the 659 or my previous receiver, the 1500; the 1800 does not have B speakers. Not a real smooth by Yamaha, although not an issue for me.
If you still are considering the 1800, go with the zone 2 plan.
