We are having the following installed:
LG B48-AWY with 2 x deluxe wall controllers 9 outlets 6 zones (max outlets 7) - $10,350
I really like the LG deluxe controller. The only downside is it only does up to 4 zones so we have to still get the 'light switch' zone controller.
Although it will cost more to install and run than evaporative, I prefer refridgerated reverse cycle. So for me it wasn't a tough decision.
