In a recent tool kit thread a few stellar members said they carry a mini-compressor. Several others on this site have also mentioned carrying one. I'm debating if I want to take up precious cargo space with something I may never need. So, for those who carry a mini-C, has anyone really needed one for other than topping off, which could be done at a service station? Those who don't carry one, anybody been stuck needing one in the middle of no-compressor land? I'm looking for stories folks. Finally, recommendations on a small, reliable compressor?
