We had this thread going comparing Boaphile to AP.

Even if you are set on AP, it should have some good info.

What heating elements you need depends on room temp etc.

I always say get heating elements for the worst case scenario. Worst case, they barely run. Best case, you keep a healthy animal in a less than ideal room temp situation.

Do not skimp on thermostat either.
