The only time I would ever really need a kegerator would be at a party. But carting around a refrigerator and kegging stuff didnt sound like much fun. Just sticking the keg in some ice and using a party tap looks kind of cheesy. I looked into jockey boxes and was blown away by their cost. Then I ran across this little bad boy, its perfect for what I want.
