Zefal HP-X. I have gotten up to 120 psi with it (I could easily go much higher but my tires can't). Manufacturer says it is good up to 174 psi.
I guess it depends on your definition of small. I was thinking seat pack small when the question was asked. I have Hurricane Air Scepters on my road bike and commuter. It is 13.5" long and weighs in at 108g which isn't too big. It is rated over 100psi and I've gotten my road tires up above 90psi with it (which was plenty to finish the ride though I could have gone more). They run it on sale for $15 quite often.
