That's the thing. I already have a herpstat, I just want to plan ahead and get a thermostat for the incubator that's going to be built at the end of this year. And if I can't run an incubator and a 5 shelf rack off of one, I need to either a) get more or b) get a herpstat pro. But the 315 bucks for the Pro are out of the question right now.
