I’ve had a pretty small response to the offer on the Datanetics PCB.  Despite the small numbers of folks interested, I’m still going ahead with this as a one time deal.  Before doing so, I’m going to spend the next couple of days looking for better pricing on the PCB.  Ordinarily I’d stick with my current fab house, since since I have had such good luck with them.  However this PCB doesn’t have a solder mask or silkscreen, so I should be able to find a cheaper place to do this board and still get good results.   Since I haven’t collected money yet – if I turn up a better price, I’ll adjust the pricing.
