Zoo Med or Exo Terra

If you're going for ball pythons then definitely Animal Platics.

Both have products that are good, both have products that suck. It's best to take things on a product by product basis. For heating pads I will say that I swear by reptile basics under tank heaters.

I'm new to BP keeping and even after a lot of reading/research thought I could make an exo-terra glass cage work with a UTH and heat lamps. It can work but it's not easy and maintaining humidity is difficult, I'm misting all the time to stay above 50% even with most of the screen top covered.

If you're on a budget go the tub route otherwise get a plastic enclosure with a RHP or UTH or both (Boaphile, Animal Plastics, Vision, Reptile Basics...)
