Actually, there are almost no reasonable job operations when the whole value of the product is low. I once started giving advise to a gentleman in the Ukraine about fixing a 115 body diesel. At first I didn't realize where he was. To him this was a piece of machinery to be preserved at all costs. To me I'd junk it, if it needed a rear wheel bearing. All a matter of priorities.
