Ok, I've narrowed down my choice to between the Circupool RJ-45 ($800) and the Intellichlor IC40 ($800). My pump & heater are Pentair, so the IC40 seems like a choice that fits the other appliances. However, the Circupool has many more features, according to this website:
So, I know Circupool reliability is unknown as of right now, since they have only been out a year or so. At the same time, the IC40 electronics are built into the cell, making the replacements more expensive. I am not going to put in an Easytouch system, so compatibility isn't an issue.
Any other reason why I should choose one over the other? I am leaning Circupool, since it has all the features except pH testing.
