I'm in Scottsdale (near Fountain Hills / Mayo Clinic) and am using the Profilux Plus II with WLAN and Redox/Conductivity cards, dosing pumps, and propeller breeze fans.
I also love the system and have no reservations in recommending it highly. It is one of the few things in my setup that has not lead to any degree of buyer's remorse!
If you really want to get it locally, check with Paul at azseabottom. He doesn't stock it but can get it. I bought mine from Aquarium Specialty, but they no longer carry the line; I know this is because the distributor is currently favoring smaller scale coral farmers rather than larger retail shops, and not because of dissatisfaction with the product.
