I just picked up a C Serpents 9 tub hatchling rack at the Daytona Expo. I am pretty excited to get it up and running but I need a thermostat. I have a herpstat 1 on my other rack, but I was hoping to not spend the money since I spent a little too much at the show ;-) Of course, my snakes' well being is most important to me, so I will spend what I need to to ensure their health, but I was wondering if anyone had any cheaper thermostat suggestions. I want something reliable that will not fry my hatchlings! Any advice, pros, and/ or cons, is much appreciated! Thanks :-)
