Having a controlled source of suction when I start stack work would of
course be enormously useful, but I don't have a surplus electric player
pump like Reblitz recommends.  I suppose I could clone one if I were
grimly determined, but I'd prefer it if my test gear weren't substantial
projects in themselves.  Are there any pumps kicking around for a
moderate price?  Failing that, are any of the suction units sold by the
PPCo. suitable for this sort of thing?
