25 smackers at Nashbar. My last Zefal lasted for 7 years and California roads are trashed to the max and I get a lot of flats because I ride sloppy. Frequently smacking Rottweilers on the snoot may significantly shorten pump life.

***I sometimes carry a CO2 cartridge with me...they're a "real gas" to use but, retro-phart that I am, always have my Zefal with me, too.
