Does anyone have any information or feedback about the Atera AnyTemp spa with the chiller and heater. I am close to my decision as I have looked at Jacuzzi 470 and Hot Springs Envoy and i like both, and will be looking at the Caldera Niagara this weekend. This Atera spa with the chiller seemed like it would be really nice in the Hot Dallas summer, but I can not find to much information about them(quality, service, etc.).
