joe blow bike pump

are the joe blow schrader/presta double pumps worth the money?

Got one, i like it, so yes.

Works for me. Scored a "Sport" on sale at Performance for 25 bucks. Puts air in the tires and has a very accurate gauge.

I have a pro and it does work pretty well. The sport has the head with two sides and the pro has a single head that works with p or s valves. The Pro's head though has a little pin for a hinge on the locking arm that likes to work its way loose and that can be a pain if you're in a hurry or you don't know what's happening - it isn't obvious what's wrong but air leaks out while you're pumping. I'd say the pro probably isn't worth the money over a sport.
