Nice thing about temp controllers is that if the heaters internal thermostat sticks on, it still shuts the power off to the heater. An aquarium controller is a better deal in the long run as it adds the function of temp controller, ph monitor, wavemaker, timer controller, ECT. Even if you don't use a light module or net module, they're still pretty awesome

if you can find a dual stage ranco controller they're far more reliable than the thermostats in our heaters and handle cooling as well. ebay sometimes has them for a good price. you can probably get an entry level apex for about the same price tho.
