There was recently a post on the KS ball forum (can I say that) from a guy that switched from Rancos to Helix's and is now saving 25% on his electric bill by switching from an "on/off" thermostat to a proportional.

I personally prefer the way proportional stats work over on/off stats like Rancos. When Rancos hit the market I tried one out and saw some signifigant temp swings compared to my proportional t-stats. Ball pythons are sensitive enough to temps that a swing of only a couple of degrees can throw them off food.

Hope this wasn't a thread hi-jack, I am honestly just trying to help.
