Well I like to give 2 opinions so people can always do what feasible at that time in their life.
I use Herpstat 2's. That way i can contorl 2 heat sources. For instance in one enclosure I have my UTH at 91 & my RHP (radiant heat panel) at 81 both off the Herpstat 2. ($195 shipped)
Also when/if you want multiple snakes you can get (2) AP T8's and run them both using 1 RHP in each for a 91 hot side wich makes the cool side in a T8 78-80 degrees.
If money is a issue right now several people use a "Jumpstart" off amazon along with a Dimmer for the 2nd heat source. Here is a link.
