Tiff + Tubs = :D

ALWAYS REMEMBER heat kills cold just slows things down.

I'd stay away from the Reptitemps. My friend bought one for his water python because (a) it was cheap and (b) it was a thermostat. What happened was his temps fluctuated all over the place, and then finally something happened where he put the knob on the highest setting (there aren't even any numbers on it) and it wouldn't go past 85 on the flexwatt surface. He ended up paying for a Ranco because he got so fed up with his Reptitemp.

My advice... if you have a job, save up for the Ranco or Johnson, and if you depend on your parents... well... make them understand that it's worth it for your snakes' health and your peace of mind :)
