My Hermes worked for me the other day.
Appear to be cheap and reliable but not fast.
I used UK Mail for 7 years with very few issues,
Fedex are good but not the cheapest.

If it is the end that I think it is then mole grips or vice grips should do the trick, however you may have to chop off the male rounded end and fit a new one using a flaring tool.
