I have a fairly large number of boards already in stock because of the way
PCB production pricing works.  I could have ordered fewer, but I would have
paid nearly the same amount.

I will look at it if I ever get an opportunity to redo the layout.  The only
potential issue is that the larger holes will prevent routing traces between
the pins.  This will make fairly large breaks in the top layer pseudo ground
plane, but that's probably not a big deal.  There should be plenty of room
on the board for a routing solution, I'm just not sure it will be one I
like.

Hmm.  When I started this project I deliberately looked around at ZIF
sockets, and the Aries thru Jameco was well priced.  I had assumed (perhaps
incorrectly) that Jameco ships internationally, and therefore anything they
sell would be accessible to hobbyists around the world.  They are probably
the premier hobby electronics supplier here in the US.

How much to you pay for ZIF sockets down under, and where do you get them?
