I am with ya Bill! I am keeping my setup as simple as possible. I have ran controllers in the past, but am pretty archaic and old school these days. Digital timers for lights, pressure fed ATO on a float valve, and a milwaukee PH controller on the calcium reactor. After a kinda rough year equipment wise, I am very much in 'control your disasters' mode. With the travel I have been having to do for work, I have to keep things as simple as possible for the wife. I did pick up one of these a while back and HIGHLY recommend it. Controlling heater temp is a battle I have fought too many times, this thing was a great $35 spent, kicks on a fan (or other cooling device) if the temp goes higher, kicks on the heater if it goes lower than desired. Simple, kinda fool proof, but pretty necessary as I dont trust the heater knob on most heaters these days.
