Cruising my local paper I see a guy in the next town advertising a tap system. It's a 5 lb CO2 tank/regulator, faucet, etc. set up in a refrigerator/freezer for the princely sum of $50. It followed me home that night.
So now I need a couple of cornies, right? Well, my neighbor was given two of them by a local restaurant that was going out of business. He would not let me pay him for them with anything except some future homebrews.
I need to have the tank hydrotested and, as it happens, I have a friend who runs a welding supply business. He's going to send it out for me tomorrow to be tested for $12 which is about half what my local beer distributor wanted.
So now I'm a kegging noob and spending time reading and searching
