I've been reviewing SWG for a couple of months. I thought I had it narrowed down to a Zodiac DuoClear and an Autopilot. I reviewed most of the ones already discussed here and elsewhere in the forum. I read all the install/user manuals to try and make an intelligent decision. I live in Phx, AZ and my pool remodel was finished in June so getting the best SWG that works the way I want became very important. I couldn't find anything about the success or failures of the Zodiac and I'm not an optimistic gambler so I decided to go with the Autopilot after reading through these great posts. Thank you everyone for helping me fill in the blanks.
