If you have a coiled cable already, I know I could make you one pretty easily and I'm sure TJ (mimic cables) could as well. If you want to make one yourself, it's a PITA if you're adding the coil to a straight cable, especially since not all cables can hold a coil. I've been experimenting with finding the best way to make my own and it's a lot of work and a lot of trial and error.
