I usually build my own rheostats but I wan't something that will controll the tempature when I'm around, also I need something so that when adjusting night and day time temps I know I can trust it will be accurate.
I know Hellix rheostats are very good, but this is only going to be for 2 cages and I don't think I could afford a hellix system anyway.
