I need a floor pump that can inflate both my car tires and my prestas. I'm considering the Nashbar Red and Orange. If I understand correctly, the Red has a reversible chuck and the chuck on the Orange fits both schrader and presta without having to reverse it. Is that correct?

I'm concerned about damaging the head each time I reverse it. But does the single head of the Orange work as well?

Would the best solution be to use an adapter on the presta valves to avoid changing the pump head?
