I'm working to select a PB and one of the builders provides Jandy and the other provides Pentair. Does anyone have an opinion on the quality or reliability of one vs. the other? Also, how does the Aqualink PDA-4 system compare to the Easytouch 4 for the iPhone interface? Pentair VS3050 vs. Jandy VS Flo Pro2? Pentair Clean and Clear CCP 420 vs. Jandy CL340? Pentair IC40 vs. Jandy Aquapure? Paramount PV3 vs. Paramount PCC 2000?
