So, what's stopping you from buying the UK$15 refills?  Or call
their USA distributor.

For vias at least, you only need one size (holes for pins is a
different story), and 1000 seems reasonable.  I just checked a recent
4.5x3.5" board and it had nearly 300 vias (12 mil) all by itself, plus
168 pin holes, a majority of which were close enough in size (28/35/40
mil) that I could probably get away with one size for all of them.

Hmmm... I wonder if we can use standard copper tubing for this.  The
issues would be (1) getting small enough sizes, and (2) cutting them
without destroying them.

(humor: I googled for "tiny copper" and half the sponsored links were
for a "mini cooper" :)
