I haven't had any problems with rigid nozzle mini pumps, but I'll add another vote for Topeak Morph pumps. I have a road morph, and while I don't flat much, when I do I appreciate getting back on the road with 30 or 40 fairly easy strokes instead of 150 hard strokes. I actually flatted yesterday, picked up a stray sliver of steel, and I was pumped up in no time.
