I use
CyberSyncs with my two 430EX Speedlites and really like them. You need to use a hot shoe adapter of some kind because the 430EX II doesn't have a off-camera terminal. I tried
this hot shoe adapter from FlashZebra but found the PC connection to be unreliable. I'm currently using
this deluxe hot shoe adapter from FlashZebra and found them to be very reliable.
I didn't want to go the cable route because I didn't want to be tripping over the cable while moving around.
