For what it's worth, my wife bought me a counter-height fridge at a yard sale for $20 that, after cutting out the shelving, fits a 6-gallon Better Bottle perfectly. The internal thermostat went up to 48 degrees at the lowest setting, so I used it as a lager fermentation and cold conditioning fridge until I got a temp controller for it.
