I too am looking for a new pump. Well, the one I have is okay. But I want another to keep with one with both bikes. Anyway, I've been looking around and I found one pump for $10- I don't like the thought of spending that much money on something I seldom use. The one I have now that has worked well enough for about 5 years, only cost me about $6. Okay, call me cheap.
But, now that we're talking about it, do these pumps just suddenly fail or are there warning signs? Does anyone have any idea the life expectantcy of these things?
