Well, just after getting rid of all my extra kegging equipment, my brother-in-law got a great deal on a fridge. He and my sister are expecting their first, and I'm going to help him get a kegerator set up before my new nephew/niece arrives. If anybody has these parts lying around, I'd love to save a dime. Nothing needs to be shiny or new--just working, not leaking, and decent looking.
