Topeak (sp?) and others make small pumps that work. I use the pump to check a patch, then use it again to start the fill and ensure things seem "right" so as to prevent the exact thing that happened to you. Then I use a cartridge to save the time of pumping, then back to the pump to top it off. Cartridges won't get most people the pressure they need but they sure can save a lot of time If I'm just on a short ride I often don't take the pump but I do take at least two cartridges.
