Hi, I want to set up a few tanks with feeders(silk worms, roaches, superworms) and I want to put heat tape under the tanks to keep it warm for breeding. I need a thermostat but I don't want to have to buy a ranco or anything just to control a couple bug tanks. Is there any thermostat that are under $40 I can get somewhere? I have seen like $30 thermostats on different sites, but found out they only show the temp, not control it. Any help would be greatly appreciated. Josh
