For anyone looking for a mini-fridge to convert to a kegerator --
I saw what I think might be a great mini-fridge for such a project at Sam's Club today. It's a 3.2 cubic foot GE without a freezer, and it's only $99. The cooling plate is flat against the back of the inside, so you don't have to bend anything down.
I was so tempted to get it, even though I don't really need another kegerator right now.
They also have it online - here's a link: http://www.samsclub.com/sams/3-2-cu-ft-ge-compact-refrigerator-black/prod1260093.ip?navAction=
(Edit: I'm not sure whether it would fit a commercial keg; I was eyeing it with ball-lock kegs in mind.)
