I agree with @lewm If you have someone in your area that know's what there doing and will take the time to talk to you about the process while setting things up, this is valuable. Unfortunately in Miami, I haven't found that person. I'd love to have a knowledgeable pro that know's vintage carts and arms around to help me with my collection. I just don't want to F something up that's in perfect condition and 50 years old!
