Before i saved for my herpstat i used dimmer-switches to control UTH (if you go the dimmer route MAKE SURE you buy a Temp-gun to accurately measure/record how hot the overall ground temp in the vivarium is. I've never had a dimmer switch fail or get to low or high on me.) . A good UTH would probably be Flexwatt heat tape IMO. For controlling humidity and temp i usually go with the Zilla 11577 (I've had great experience with it) Also i wouldn't jump into breeding so soon.
