Herpstat Pro ?

This is highly dependant on what you are trying to do with all those UTH's. There are probably better ways to heat your cage than using 4 UTH's. But to answer your question, you could use one thermostat for all like heating elements. So if you keep the 2 small UTH's at the same temp, you could use one tstat for those. Same goes for the medium ones.

And so if you indeed have two like UTH's running at the same temp and two identical UTH's running at another temp, you could use the Herpstat II.

I like the idea of using an RHP myself. An 80watt would do nicely and bump ambient temps as well
