Noticed the AC3 is no longer being sold at Marine Depot, Premium Aquatics...etc. Even the Neptune site no longer lists it. This would really suck since there would be no "middle of the road" controller sort of speak between the Jr and the Pro. And updating to the new Apex will cost a fortune since none of the peripherals for the original AC line are compatible with the Apex meaning I'd have to buy an entire new system. Please correct me if I'm mistaken. Thanks.
