Where can I purchase a thermostat?

[icewb8]

Hi I built my own styrfoam incubator and I was wondering where I could get some type of thermostat to control the temperature. It is heated by a single bulb. Thanks

I built one as well and I bought a dimmer switch ($5.98) that screws into where the bulb goes and then the bulb goes into it. I have my thermomter and off I go. I want to get a water weasel. I guess that you put the temp reader into it and it tells you more of the temp on the inside of the egg, not just the air. I made one out of plastic bags with water in them, I guess it's the same thing?
