Ditto with what Waterbear said. I was purchasing a controller anyway and the SWG was only $400 more so it was a no brainer for me. I would easily pay for that in chlorine over the life of the cell.

The Aqualogic is pretty a good value and had everything that I needed. But the main reason I went with the unit is because all of my equipment was Hayward and so is Goldline so I got an extended warranty for free.
