Huh. Seems that vacuum pumps aren't cheap. At least, vacuum pumps that pull down to 10^-4 Torr (0.1 micron Hg) aren't cheap. So far the cheapest one I've found is a used one for $100 that supposedly "works ok".

On the bright side, I did stumble across this site full of all sorts of interesting stuff: http://www.ecu.edu/glassblowing/gb.htm

(Hmm, I wonder what's a good place to find sheet nickel...?)
