I found a wine fridge on craigslist for $30 that works wonderfully, the temperature is adjustable from 45 degrees (F) to 60 degrees. I only have to worry about humidity, which hasn't been too hard, just by adding a small pan of water in the bottom of the fridge...The only real modification I had to make with it was replacing the shelves-the originals were wavy shaped to accomodate wine bottles. I currently have 4 small wheels and two partial medium-sized wheels in it with a little room left for more!
