Pretty quiet here lately, so I thought yet another question from me wouldn't raise too many hackles...

As I mentioned in a previous thread, I've set up a Zone II on my deck and now I'm wondering about my options for controlling volume on the HK 635. I know about the A-Bus module (AB1), but that would require Cat5 wiring, and mounting a plate outside, etc, not to mention another $100+. Not a very good option for outdoors. Anyone have good experience with and/or a recommendation for IR relays and such?
