I was looking for something to use that was readily available locally. Most importantly something that could pass undetected by the SWMBO in the next trip to the home improvement store.

I've never gone below 60 for a ferm temp before and have no plans on doing a lager in the next year. If I upgrade in a year I'm only out $25.
Edit: Opps looks like that ebay link is for a 100-240* range controller.
