Control cable supplier other than RadShack?

I need various length 5-12 volt mono and stereo inter component control cables. Radio Shack only has 1' and 6'. I fabricated some with RS solder and screwed ends, but the wires are so small, I'm getting shorting problems and need to go with a factory molded cable. Thanks!

They make all kinds of high quality custom cables. I've used them, and was very pleased.
CAT-5 with chopped up mini-plug cables works pretty well.
Shorting will not be a problem if you strip back enough of the outside sheathing on the mini-plug cables and use lots of electical tape. Because the CAT-5 conductors are solid it makes it a little easier to work with.

Good luck!
