BnK CT multizone receiver, (2 way feedback only for 6 zones, unit cable of doing 12 mono if desired), works great. Iport iPod dock works great. Heard that the Escient dock takes a while to download all data, and you can't access things for several minutes after being docked.

I have had good luck with in wall and remotes. T3-V 2.4 and T2-C 2.4. T2-C seemed to be a bit quicker, more reliable, but both worked good once antenna was in good location. Used T3V to access front door camera via wifi netwok, this sometimes doesn't load, and you have to go back to the page to get it to load. No problems with that on the inwalls.

Zigbee not as forgiving as 433, but if you play with antenna location it does seem to do pretty good.
