Good luck a small wire chopping line starts at a 100,000 and the bigger ones are a half million a piece. Do you live in a heavy industry city or more commercial and residential is the first question you should ask yourself. I know a yard in ohio that owns a chopping line. They only thing I remember him telling me that the only wire it ever meet that it couldn't chop up was 4 inch line coated in a hard heavy tar. It just gummed up the machine and stopped it cold. Other then that it would eat up anything you would feed it.
