I have a small fridge that tightly fits a tall 7.9 gallon bucket. It's larger than the usual small fridge but much smaller than a regular fridge. Found it on craigslist for $40. Some guy was using it as a kegerator so it has the hole drilled in the top. It fits corny kegs (barely) so it may have a future use as a kegerator. Like everybody else I run it on a digital controller.
It doesn't get cold enough to lager and I don't keg to justify a chest freezer so I can't lager beers properly. I can get beer down to the low 40s which gets me in the neighborhood of a decent lager. So what you brew makes a big difference in which option might work best for you.
