Haven't tried one yet that I well and truly liked. However, there are some bright spot through the dark clouds: zefal makes a nice pump that screws onto the valve stem with a flexible hose, which saves all kinds of trouble. It's piston rod rusts easily, however. My little merida pump has a nice gauge and a toggle between high volume and high pressure modes, but I can't get it to work over 40 psi with road tires, which just plain blows.
