I've got a medium Lezyne Pressure Drive: it's very reassuring looking! I've only used it a couple of times but it was pretty quick (and I'm a weakling!)
Lezyne make some vague claims about their pumps, e.g. "20% more pumping power than most frame pumps" for the 'road drive', and "inflates to riding pressure quicker with 30% fewer strokes than conventional pumps" for the 'pressure drive'. Can anyone who actually has one shed light on the basis for these claims? From the little I can find out online they look like very shiny but otherwise completely conventional single-acting pumps.
edit:
I feel this thread needs a link to the mini-pumps thread. The second page has one of GA2G's lists.
