I'll add to this as well. Seems the U.S. Post Office used the box shipped from PrairieDillo to me as a tackling dummy. It was all but shredded on one side and I feared that the two boards inside would be damaged. Not the case. He packed the two PCBs so well, they were protected from harm. No damage. Both worked fine in my machine. Kudos to a great seller and a great PCB packer!
