Hi, Here is a cheaper option for the bits you are after..
I'd consider the 3.5mm 'miniphone' sockets & plugs, they are MUCH more reliable than PC.. I find I'm always trying to wiggle the cables to get PC Sockets working.
If you go PC from your Camera PC socket, use a screw lock type to prevent it falling out all the time. So I would recommend Screw type PC at camera end to 3.5mm miniphone jack at flash hotshoe end.
Colins photo are cheap and I've found the dozen or so bits & pieces I've ordered to be of good quality, very happy with his service and postage costs too.. He's managed to get parcels from UK to Australia in under a week.. Only B&H have service like that but you pay thru the nose for it...
Edit, found him on the Web if you don't like that auction site...
