What is the best floor pump? I'm looking for a pump at home to use with my high pressure (100-120 psi) road bike tires.  My bike has presta valves, but I would like to be able to use it on Schrader valves, should I get a bike with them.

Who has a floor pump that they like?
I have a Specialized pump which works very well for both high-volume and high pressure tires. 

I've also used a couple of different Joe Blow pumps from Topeak, which worked pretty well.  

In light of this, I'm of the opinion that your best bet is to hit up your LBS and see what they have, and what you like using.  For me, handle shape and size plays a big part (you need comfort to pump up a 26"x4" tire).  Plenty of pumps work for both types of valve, and your LBS should be able to point out which pumps can do this.  Some require you to screw off a cap and flip something over, others can have a two-sided head, and others (like my Specialized) have a head that works for both without any changes.
