The PA-09 crimps mentioned above are PRICELESS for these connectors. I tried a cheap pair of cheaper crimps and they were garbage. I highly suggest the pa-09. I picked mine up from adafruit a long with some 10k pots and ok looking knobs for cheap. Getting the crimps from adafruit were really fast because of where I live but I suspect that they'd ship anywhere in the lower 50 faster than anyone in china could get them to me at roughly the same price.
