As far as thermostats I would stay away from zoo med and zilla, I've owned them both and returned them 2 days after I had them, they drop 4-6 degrees before they start heating again and that's really not good. If you can't get a proportional thermostat right now and have to get an on/off get one that only drops 1 or 2 degrees at most before it starts heating again. One option is if you or someone you know can do basic wiring is get an STC-1000 from EBay and a short medium duty extension cord from a hardware store, all you have to do is cut and splice extension cord and wire it to the stc-1000 and you have a cheap on/off thermostat that only drops 1 degree before it turns heating device back on. Make sure you get one that is 110v if you have 110 electricity. You can use this thermostat for uth, che, rhp, heat cable, heat tape, any non light emitting heat source. The reason you don't want to use on/off thermostats for red bulbs and other light heat source is bc they will constantly flicker on off, you will need a dimming proportional for light emitting heat sources. Pulse is also a good thermostat bc it will keep one constant temp but it is also only for non light emitting heat sources. Dimming can be used for any heat source.
