You could also watch ebay, I've seen a couple sell there. And try www.markertek.com , I think they carried it at one time, but I'm not sure. VDC might have some kicking around. I think the connector is an industry standard one, if you have the pinouts, you could also make one. The cable only has RGBS and a control line in it(I've cut the end off one) so only 5 of the pins are used. I think you coudl even determine the pinout by tracing the leads in the switche itself.
