It gets very hot where I live, so I invested in a freezer/controller setup. I paid $100 for a freezer off of craigslist, and $130 for the 2 stage digital controller. If you find a smaller/cheaper freezer/fridge and buy the $60 analog controller (or $80 single stage digital) you could knock that price down a bit.
It's awesome not having to worry about ferment temps at all, though.
