You could try Newark (www.newark.com). They're part of the Farnell
group (www.farnell.com). Farnell sell Greenlee and a couple of other
good makes (search for "connector punch"), but in North America they
sell through Newark. Newark tends to be a bit expensive, but they will
take phone orders and do ship to Canada.

About double that now.
I'm not surprised. I would be suspicious of
anything under $100, and I
expect to pay more like $200-$300. (If I go ahead and buy, that is.)
I'd be slightly concerned about repeated drilling
through the template
enlarging its holes slightly each time the drill bit brushes the side
of the template hole; I might make my own duplicate template....
You can buy spare templates for a few $$ each.
Incidentally, is anyone familiar with a treatment for
aluminum that
renders the surface nonconductive? The housing I made this hole in is
made of aluminum - but I got a surprise when I was working with it and
checked resistance to the housing and got infinity (which means more
than about 40 megohms, for that meter).
Anodizing will do that. Aluminium oxide (alumina) is a good insulator.
The oxide will form naturally on the surface, but anodizing gives a
more even layer and is a common treatment.
