I had been considering buying a small stock of copper clad boards in so
that there would be some to hand when people wanted it, but its sold in
so many sizes i was having trouble figuring out what would be the best
to go for.

I also read that FR2 board is considered better for milling, as its
easier to work than the now more common FR4 fibreglass boards.
