So I finally bit the bullet and bought the Lezyne Classic Floor Drive, after trying out the Beto and Zephyr from MEC and having both fail (the Beto chuck actually exploded on me). In short, I'm quite impressed, the thread on chuck is honestly the best designed chuck I could imagine. So much better than my last pump. Still looking for a carry-along pump, but I think it can wait for a bit now. Thanks for the help, everyone.
