I have an All-in-One(AIO) and an inline house filtering system (which I bought from FiltersFast), and Steve walked me thru everything...as we talked on the phone. Later that year I received a MiniJet as a gift. I much prefer the All-in-One setup. But if I had not known about the AIO, I would have bought the SuperJet, simply because the Mini is really not meant for volume work, while the Super easily accomodates 100-200 gal/year. Plus, you get great customer service from Steve.
