I've used a win cooler for getula w/ some success. Cost like 200 bucks.

It doesn't get below mid high 50s though, and it's small. I'm looking for a way to do more of them myself. I have a small building, but it's got retics in it too--can cool it too much because of them. I'm still playing with things to see if I can get a more economical way to burmate animals.
