Looking to get a enclosure set up for a Young Ball Python and want to avoid over/under buying and would like to have it cost under $150

Are the “Starter Kits” Worth messing with if they can be bought new for half price or $99 shipped

It would need an additional hide and a thermostat to meet some of the recommendations I have read.

Buying everything separate is fine also if it would be better for the animal and myself and if the budget needs to be higher that would be easy also.
