I like the Lezyne Road Drive. I have one in the medium size, and recently ordered one in the large size.
I have a frame pack that hangs underneath the top tube. It can accommodate one of these pumps, spare tube, patch kit, tire levers, small multitool, etc., along with my flip phone. I keep my Topeak SmartGauge D2 in there, too; not terribly concerned about the grams.
