I'm looking for a beer fridge to keep in the garage. I have a large variety of micro brews that need a cold home. I was looking at freezer-less fridges, but the stability of the shelves worries me. I was also looking at some user TRUE commercial coolers, but that seems like overkill too. I also noticed that it looks like a lot of people have re-purposed some old freezers for this purpose too. My questions is - what have others done or what is the best solution in the $500 - $700 range?
