If you are just going to have one or two clutches then you don't need to spend that much money - your major purchase is going to be your thermostat - a Helix will work great and is $125ish.

From there all you need is something that is insulated and will maintain a steady temperature - a hovabator, cooler, broken minifridge, styrofoam shipping box - all really cheap (free if you know were to look) and will work great.

For heat you'll just need a little flexwatt, or heat rope (if you decided to go with a hovabator it comes with heating element).

And then you are good to go.
