i recently checked out reptilesupply.com and saw they had ESU Thermostats for around 25 bucks....are these things like total junk?? like should i not even bother with it? i would just rather spend 100 bucks on thermostat, heat pad, substrate, moss, and some lights, rather than 100 bucks on thermostat and heat pad. If it's really just a piece of crap, i'll go to reptile basics and get the goods.
