I have a SWG and the Jandy PDA system and have no problems. I can run the SWG on 15% during the summer and am fine. I do have a small pool and a low bather load. However, I feel the Jandy PDA is very old school (like the flip phone analogy) and knowing what I do now I would go the iAquaLink or go completely Pentair because of the great reviews here. (I can upgrade to the iAquaLink but don't really want to spend the $$.).
Addendum: when I say no problems I mean with the salt system. The PDA itself is fickle in that sometimes it won't come on, it just says "waiting..." And you can only adjust settings using the PDA.
