I am considering purchasing an Einstein to go along with my 600EX flashes. Paul Bluff has suggested I get a CyberSync to plug into the PC port of my camera body and then another CyberSync to plug into the Einstein. I could then leave the ST-E3-RT on top of my camera body. The problem I see with that is that the CyberSync would just be dangling from my camera body.
I'm wondering if anyone else has found a cleaner solution to the above. I remember someone posting some photos of a shoot-through transceiver that sits between the camera body and the flash, but I can't find the photos anymore.
