That thermoSTAT for the UTH is the most important piece of equipment you need to get right now. Without one the UTH can get hot enough to burn your snake in just a few minutes. The vet bill to treat a burn is many times the price of a thermostat.
Hides are easy to make, put some loosely crumpled-up paper in there for your snake to hide under, and call it done.
