Topeak RaceRocket HP and the longer HPX. No problems after several years of use -- including many inflations on the road for my own bike and other folks in a group ride.

The Topeaks have, by far, the best ergonomics of any mini pumps I've tried. Big, soft rubbery grip on one end, soft plastic rounded button on the opposite end, that make it a bit less of a chore to pump up near 100 psi. Lightweight, rugged, smooth operation, extension hose stays attached to the pump body, threaded chuck is convertible between Presta and Schrader.

For hybrids, mountain bikes or any tires that don't need to be pumped to 85-100+ psi, go for the other Topeak RaceRocket models with fatter diameter pump tubes. But I've used the RaceRocket HP many times for 700x38 and larger tubes/tires on hybrids. It just takes many more strokes, but at very low resistance compared with high pressure road bike skinny tires.

I tried the Lezyne and didn't care for the ergonomics and fiddly disassembly (the hose is designed to be removed for storage when not in use), although they were excellent quality.

Same with the longish Blackburn equivalent to the Topeak RaceRocket HPX -- excellent quality, but ergonomics were compromised for the sake of a streamlined appearance. No rubbery grips. Sharp metal edges on both ends. A bit more of a chore to pump high pressure tubes/tires. And the chuck turned out to be Presta only, not convertible like the Topeaks. I keep it on one road bike.

On the plus side, the Blackburn included a real and useful metal valve stem tool, threaded into the end cap. The Topeaks claimed to include Presta valve stem tools but neither of mine did -- just soft plastic butt caps.
