For a decade and a half or so I carried* the two-stage Swedish Quicker Pro, praised by Compass Bikes and Velo Orange back in the day. I'm not sure if it's available anymore; a 'net search indicated 'no'.
*Shrug. I maybe pumped two on-the-road flats with this. I don't get a lot of flats. I dunno. Seemed okay, but I didn't name a child after it or anything.
