The material Mike used (High silicon moly ductile iron) drastically increased the cost over what he could have used. Over time cheaper materials will snap studs with the expansion and/or crack. His margin at this point makes the product not worth producing. He honestly has not profited from selling these to this point. Mike is a GREAT guy and would go out of his way for anyone. It is truly a shame he could not make a reasonable profit on this project after all his hard work :-(
