I live in St. Louis and recently purchased two used kegerators from a friend whose sister worked for Anheuser-Busch, just right up the road from my house. I ran into quite a bargain -- I got the pair for $100 total.
The Kegerators have some mileage on them (originally used for catering at A-B), but both seem to cool just fine when plugged in. The motors and refrigeration units aren't a big concern at all...
What I am curious about is a complete replacement of hoses, etc. I would ideally like to install my own hoses to run from the faucets to the couplers before running beer though the existing line (the kegerators have been dormant for a good 3 years) - nothing quite like that dusty taste of beer, right?
Is this a difficult process? What kind of tools will I need to get the faucet apart and the existing hose removed? Also, would it be advantageous of me to replace both couplers? One looks okay, and the other looks, well, rusty.
Thanks for answering my barrage of questions!
