Okay - I know this has been asked again and again, but I can't for the life of me find an old thread on this. (I am bad at that sort of thing)

What do you guys recommend for a thermostat for a ball python set up that uses exclusively UTH? I have a bit of money to spend, but I am not looking for the "uranium pu-36 explosive space modulator" version. I want the thermostat that you think is the most reliable for the money.

Any suggestions?
