here in the US they're $40 new and usually $30 used, but I found mine for ten. (By the way, the RC1000L and S work for all Maxxum cameras, and the Dimage as well)
Hi the short one costs abt $55 and the longer one $60-$65 from fotoguide 3 months back. but frrankly, there's no need for that much cable (long one), unless you're shooting birds, animals or as such...
