Price Computing Scale Sample Leads

Need a low cost scale which can calculate cost and display to customer

It will weigh 90% silver coins and display weight in ounces, troy ounces and actual silver content. Ideally it will also caclulate a price based on current market spot price and premium (either manually entered or picked up globally). I would order a large quantity. Desktop size, 1 oz to 60 lbs.

I really like the CAS 2000jr because you can add a label printer later. I need this to weigh chickens, turkeys and other meats at farmer markets. I need it to go up to 60lbs.
