I have not used anything other than the Helix for the incubator. So I dont know, I know there are others out there. That work just as good. For the incubator you dont want one of the on/off type of thermostats. With thoses I would think you will have a hard time keeping steady temps. Like said go with a proportional thermostats. There is other proportional thermostats out there other than Helix. Im not 100% sure what they are or how much they cost.
