I have this Topeak:

I like the gauge feature. It will get my 700 X 38 to 50 pounds fine. Anything higher and you will have to wear yourself out doing it. I ride at 70 PSI but on a flat I am willing to go with 50+ to get me home. I also ride with CO2. I have the pump only for Rails-to-Trails rides where I am in the boonies miles from any support. Meaning if CO2 does not cut it, then the pump will.
