I'm using my SB-800 off-camera, but the 4' cord on my SC-17 isn't long enough. Does anybody either have instructions on how to put a longer (20-30 foot) cord on it, or know of someone who does that kind of work (need I say, cheap?). I want to retain the TTL capability of the flash and am not ready to go down the Pocket Wizard route just yet. I need to know a source for the cord, as well. David Hobby recommends CAT 5 cord, but I don't think it has the 6 cables necessary that I see when I open the SC-17.

Thanks in advance!

Karma at work:

The same week I posted this request, I found this:
The Strobist Corner - Extending Your TTL Flash Cord | DIYPhotography.net

I built one and it works. There was one glitch that the author didn't mention. The cord is surrounded by wire shielding and one of the wires has bare wire surrounding it. I twisted the shielding wires and plugged them into two slots on the CAT5e wall bracket, and it worked just fine.
