A while back I showed you how to modify a Kaiser hotshoe to replace the PC plug with a 3.5mm jack. If you are rubbish with a soldering iron then there is an alternative for you.
The Flash Centre have had a special run of Kaiser Hotshoes made pre-modded with a 3.5mm jack plug that will connect to your Elinchrom Skyports or Pocket Wizards. I cannot recommed a more secure way of connecting your flash trigger than this. No more unreliable PC socket to worry about. However they aren't cheap, they cost about three times the price of the DIY version.
The feet on these things are removable, so you can configure it with a hot-foot or a tripod mounting socket.
