Lezyne Pressure Drive Handpump; S**t. Recommendations for replacement?

Hit a pothole this morning; broke a spoke nipple Crying No problem, fix it in my tea-break, got my CO2 inflator Cool Except the one year old CO2's seals had perished, the CO2 came out the wrong end and froze my fingers to the cylinder Crying No problem, I have a nearly new Lezyne Pressure Drive hand pump Cool Except the connector is already knackered; despite only having been used a few times Crying Useless Crying Can anyone recommend a hand pump and/or a CO2 that actually works more than once Thinking
