Hello-new to brewing but have desire and have read some so I know enough to get in trouble. After consideration I have decided to purchase 2 corny kegs and need advice on which is the better set-up-pin lock or ball lock? If somone has suggestions on a good cheap way to locate 2 kegs- I am open for suggestions. I am fortunate to have an old refridgerator in the garage and plan to modify it to house the cornies. Thanks for your time. D
