Adam,

Another, even easier, source for free vacuum pumps is dead window air 
conditioners.  Most often, folks toss them because they developed a leak 
and lost their charge of freon.  That takes care of the concerns about 
venting the stuff to the air.

This time of year, lots of folks are tossing the summer's reject A/C 
units.  Check the curbs on trash day, or your local trash dump.
