I start with a wine whip (well, a cut-up plastic hanger I made myself) attached to a cordless drill, and after a couple minutes of that to get most of the CO2 out, I finish with a Mityvac.
I like it because it actually has a vaccum guage, and can pull a much harder vacuum than the foodsaver or a vacuum cleaner. I pump it down to -23 or -24 inches Hg, then when the vacuum drops to -15 or so I'll pump it down again. After the first few cycles, less gas will come out, and pretty soon it will keep the vacuum pretty well. Leave it like that overnight and you know it's done.
