I know there's a ton of topics out there on this subject but I got really overwhelmed wading through them and I thought I'd ask specifically about my situation. Sorry about the redundancy!

I have one juvenile ball python (Freddie!) in a 20 gallon long. There's a UTH on the hot side and a light fixture (60 watt red bulb) on the cool side. I have almost no issues keeping the cool side at about 82 degrees but I experience (minor but still...) fluctuations on the hot side.

I want to invest in a good thermostat (not a rheostat or dimmer). What kind would be best for my set-up? Is it possible/should I hook both the UTH and the light up to a thermostat? I am not savvy with electronic devices at all and I need all the advice I can get on this.
