So, I searched to see if I could find a thread similar to what I am looking for. Anyways I only have one of those cheesy, stick to the glass thermometer/hygrometer, and I really need to upgrade. My snake seems healthy and fine with the temps/humidity...I was just wondering if anyone has any specific suggestions for a thermostat (that I can buy online...preferably cheap-ish). I want one of those probed ones, that shut off my lights if they get too hot kinda deals. My tank is a 20L glass reptile tank. I use a small (10-20 gallon) UTH, and I also have his day/night lights. My apartment tends to get chilly in the winter because it's drafty, so I just want to make sure he's warm enough (for sure...instead of just guessing or going by the cheesy plastic temp guage). Any specific ideas online that are also fairly cheap? Links would be good if you have it.

Thank you!
