The lezyne floor drive is the best pump I have ever used. The thread on presta head is the shit. Similar to silca, it can be 100% rebuilt. I am done with the crap plastic heads that all these other pumps have.
I keep buying Joe Blows because they are cheap. Reason I get Cheap ones you ask? Because I have a habit of leaving my pump behind the rear wheel of my car, then backing out, running it over and destroying it. I think Iv'e done this like 4 times...And I don't even smoke the ganja!
another vote here for lezyne, i have a park tool one that resides in my car, but once you get above 40-50psi air leaks through the cylinder, probably needs a rebuild but it still works fine for my mtn bike so idgaf
