I recently bought one from American Brewmaster mail-order after seeing their ad
in the latest Zymurgy. If you can find it in the air-conditioning section
of a hardware store like Keith did, you'll save a couple of bucks by
eliminating the middle-man. Williams charged me $29. Works great.

Anyway, here's a related story. Now that it's a little too warm to ferment
for us basement-deprived brewers, I decided to make use of that little
refrigerator I had in my college dorm way back when. It's much too small
for a 5 gallon carboy, so I removed the door, made a wood-frame box,
lined it with 2-inch stryrofoam, weather-stripped its face, and butted it up
against the little fridge. The top is removable, and I secured it to the
little fridge with bungee cords. I plugged the fridge into the temperature
controller last night. I easily maintained a temperature of 50 F for its
first test.

I'm curious to see how cold I can make it. The entire unit sits on a
shelf in my garage. When comparing it to a full-sized fridge, it's a
great space and money saver.
