Thanks for the suggestions. Yes, I'm talking about a frame pump for occasional use after flats, with my floor pump doing the normal stuff. Where I used to live there were a lot of goat heads and I got a lot of flats. Fewer now, so don't need a pump that will inflate 10,000 tires from empty, but more one that years later still works fine.

And forever? Well I exaggerated a little. I'm 66, so forever can be quite a while, but no one lasts forever.
