Motor cable

Hi,
I have my Sherline/Xylotex/Mach1 system up and running.....finally! The
cable I found and used for the leads to the motors from the driver is 4
conductor, foil shielded with a ground lead next to the shield. The problem
is that this cable is not very flexible.
Any suggestions for a more flexible cable and where to get it? I would like
to get enough and of a suitable size that I can use it on my BP size
mill/drill later on. I will probably use steppers on it also.

Thanks, PJH
