I'm curious if anyone has tried using a big router with a carbide or 
diamond bit and a template to do the odd shapes.  Of course, the 
advantage of punches is that a smooth edge is the result.

I recall that the model shop guy at one location where I worked didn't 
fool with Greenlee--he said that they were probably fine for field work, 
but he relied on his Pexto punches (now part of Roper-Whitney) to do 
that sort of thing in the shop.  I suspect you'll find a Pexto or close 
relative in most sheet-metal fab shops.
