Make sure you do not get a pump with overly large diameter pump tube as they are harder to pump to high pressures because of more resistance. Selecting a good pump seems to be hit or miss though as I have encountered pumps with plastic bodies that work very well, like the mostly plastic floor pump from Zefal I used for almost 20 years without problems. Zefal just knows how to design good pumps. In contrast I bought an OK looking pump to replace the Zefal after it's hose finally died on me. It's a small OD bodied steel pump by Schwinn that I bought from Target to save some money. Had all the bells and whistles and seem to feel and look solid enough for the job (How can anyone really screw up on a floor pump design these days??) but it turned out to be the worst floor pump I ever encountered with very hard effort pumping because of what seems to be some internal problems with the valve head, and the valve head refused to lock on securely to the tire valves, for some reason always blowing off the valve at exactly 95PSI and it died about six months after I bought it with a fatal leak at the pump base assembly.....Yecchh!.
I will not hesitate to buy another Zefal floor pump again if I find a new one for sale because you can't go wrong with them, plastic or not!
