after doing some reading i have decided to buy a thermostat i want one that is within my reach 100 dollars maybe but not to cheap, also are repitherms any good.
I don't know about reptitherms. If you want a thermostat for regulating the temp in the cage, you could also do well with a Alife or ESU which actually cost only about $30. If you want to regulate an incubator (or a heater as well) you need a proportional thermostat. The best price I found a few years ago was the Big Apple was made by Big Apple Herp which you can find on-line.
