I had to burn 1500 usd cards a few years ago for a project. Bought a 10 port USB splitter and 10 USB-uSD card converters. Wrote a simple script that mounted, dd'd, verified, and umounted whatever was in there. This thing is bound to be much faster, but really - the cost is in the labor. My biggest cost savings was in buying the cards on pallets, rather than having to shuck them from packaging individually. The time to stick all the cards in the slots, and pull them out afterwards, dominated all costs associated with duplication. If I had to do it again, and IF I could have frozen the image in time, I'd have just paid a duplication company to burn them. The cost for that was smaller than the cost of the cards.
