when i ran a bike workshop, we used to go through pumps like nothing. too many junior staff, volunteers and kids man-handling them, there would always be a bin of them with ra tags waiting to be shipped out. so i bought a couple of those beto ones from mec (just up the street) and would get someone to ride over and return one as soon as it started conking out. we probably did that a dozen times before they got wise and cut us off, but it was a sweet 6 months! the kicker is they donated all of the returned pumps back to us the following year, spare parts galore. i still have one with a bent shaft that i'm using 5 years later
