I've ordered the flex PCBs from OshPark and the components from Digikey.  I should have them within a few weeks.  Next update will likely be assembling one.  I have not ordered an SMD stencil yet.  Since the flex takes a little longer to arrive, I thought I'd spend the next week or two experimenting more with laser cutting or vinyl cutting a stencil from Kapton or mylar.  I've had some success in the past, but these are small parts..
