I have a both a Zefal and Road Morph (among other pumps). The Zefal isn't too bad for completely filling a empty tube after a flat fix or a tube change, but its a pain in the ass compared to the ease of the Road Morph for topping off tire pressures every other day or so on a tour. The Road Morph has a built in pressure gauge and the mini floor pump action doesn't risk tearing off your valve stems if you get a little over zealous at high pressures.
