Based on what you guys said and on the fact that I'll probably ride my bike quite a bit, I'll probably have to buy a floor pump. Thank you all for bringing the various brands to my attention. I'm still leaning toward the Silca Pista. I hadn't heard of the Lezyne, sounds like the Cadillac of bike pumps. Probably a bit more expensive than I'd like to go. Are replacement parts for Lezyne pumps easy to order? Is a Lezyne pump similar to a Silca, where all the parts are replaceable? Thanks.

EDIT:
Here is a semi-cheap one. Is this worth it? I have a Giant Escape 2 Hybrid bike. I think the max PSI for my tires is 60
