Quote: 5. Cost versus benefit/sales volume - Can Chiefs really be commercially made at any useful sales volume or profit margin? Kevin's Chief has set the bar in Chief size and quality that may never be beaten. But could he make an order of, say, 250 units, and make anything like a profit? I would estimate no, it would not be a profitable commercial product.
