I'm very new at this and want to get all the information I can to do this correctly and keep my new snake as happy as possible.

I am told that the most common way to heat a ball python's habitat is to use a UTH.

Do UTHs come with thermostats, or do you have to buy them seperately and install them yourself?

If you have to install them yourself, how easy is the installation?

With these thermostats, will I need additional thermomiters to guage the temperature more accurately?

How much will I be paying for a decent thermostat?

One final request, please point me to a website where I can buy both the reliable thermostat and UTHs
