What's wrong with the Best pump?
It seems okay to me.

The prob with the wal-mart pumps is that they can't pump up past about 7 psi without either the handle or shaft snapping or it leaking from the bottom and not keeping up enough pressure.
I use to use walmart pumps exclusively (Ozark Mountain Trail), but the new kites need more than 6 psi (the old ones didn't). Once I started getting one pump SLE's, I started breaking the walmart pumps about every 4th time out or so.
I hardly ever break most kite company's pumps these days.
