I have two Medium sized Road Drives in both carbon and aluminum bodies; excellent hand pumps for 700x23 tires. One is equipped with the optional Pen Gauge hose with integrated pressure gauge, which is awesome, because it takes the guesswork out of mini pump inflating.

Of course, not knowing what you don't like about the Spin Doctor makes it impossible to say if a Lezyne will be better suited, but I've got no doubt that the Lezynes are better tools.
