Update 5-July-2013: It has become impossible for me to keep up with orders for these circuit boards. To date, each and every one has been built by hand in my small shop, but demands on my time are simply too great to continue "as-is." I am exploring other ways to get the soldering done while trying to keep the prices in line with where they are currently. I apologize to all who have placed orders and subsequently received a refund without explanation. I hope to have this situation resolved later this summer, but for now I cannot accept new orders.
