I'm pretty sure I ordered mine through Mouser with no troubles. You get a price break at 100, but I believe you can order individual units. At any rate...
I have a spare S760K. Picked up 3 at some point: one for my hacked right-angle power cable, another hacked as a backup cable, and a third (unhacked) as a spare for future, better hack jobs. You're welcome to the third, unhacked connector. PM or email me with your addy.
