I'm trying to invest in one for my ball python and another in the near future once i have enough funds saved up, but the question is: Are there thermostats that have multiple probes? for at least 2 or 3 cages? I've seen the prices on some of the highly recommended ones and they are at least $100-200! I need something that is the same amount but can determine temps on multiple cages and not just one. Can someone help me?
