I use a Lezyne Digital Drive 18k floor pump with the optional "Pro" Presta head. If you are running Presta valves, this pump (or just the head), is a fast, no-nonsense component which you don't have to fumble with. I like that I can put it on and take it off without losing any air, and that the pressure gauge is accurate. This pump was expensive, but with half a dozen rather expensive bikes, I thought it was a good investment.
