Nashbar Earl Grey floor pump for $30 is a great value. Very solid. Been using one for several months. The gauge is accurate enough for my purposes, and within a couple of psi of my other pressure gauge. The lever lock head isn't as easy to use as a threaded or quick attach/detach head, but it doesn't bother me enough to replace the original head.

The Lezyne Steel Drive floor pump includes a threaded head, gauge and bleed valve, and reviewers rate it highly. Looks good for $50-$60, and might be worthwhile for a shop or folks who own several bikes.
