there is a huge difference between a well maintained piece of equipment that needs repair, and something that has been allowed to corrode into a solid piece of rust. The issue is labor. If it is your own machine, and you don't mind spending the time as a hobby to get out of the house, it works out well. But if it is a machine that needs hours of labor to get past that lack of maintenance, the lack of quality new or used parts, etc., fixing it for someone is a charity case. If that is the goal then it works well. But if it is being worked on for profit, I still believe it should be sent to salvage or sold to someone who is looking for one and has time on their hands.
