I bought one of these on Ebay for around 10 bucks. They will control temperature as relayed by the included probe, by heating or cooling, depending what devices you have hooked up to it. Max current is 10A.
In my case, the heating device is the tractor block heater, and I have set the controller to keep the block temperature at 0 C with a temperature differential of 2C. If it is warmer than that outside, the controller tries to turn on a cooling device, and since there is no cooling device connected, it essentially does nothing. When the temperature drops to less the 0C, the controller keeps the the block heater functioning only enough to keep the tractor engine at 0C.
This saves quite a bit in electricity costs as the block heater is not on all the time, only when needed.
