Lezyne, also. They come with a mounting bracket that installs on your water bottle bosses (while still allowing you to install a water bottle cage).
Since I run 28mm tires and top out under 70psi, I went with an HV model so that inflation doesn't require as many strokes. Previously used an HP model; it worked when I needed it, but mini pumps in general are such a pain to use on the roadside that it (along with my flat frequency) spurred me to make the move to tubeless.
