I have gotten several suggestions on rheostats and thermostats to use with my under tank heating pad for my corn snake. I would like to know the difference, pros and cons, what different people use, recommend, and where to buy it. I saw some that you had to like open up and rewire, that is NOT for me. I live in an apartment, I don't need the stress of worrying that I will burn down the building, I need something widely used and available, reliable and relatively inexpensive.
