Hmm, that one does look promising.
I keep eying the mini-fridges that keep appearing on Craigslist (university town, so we have considerably more of those than full-size units listed), but they tend to have a compressor taking out a nice chunk at the bottom and are usually too short for a fermenter with an airlock above that point.
Probably obvious, but if you can go to the store, bring along an empty fermenter WITH an airlock (assuming you use one) to see if it fits.
