Please suggest the best and most affordable way to trigger my 430EX-II off-camera. I have a clumsy sync chord which hardly extends beyond 2-3 ft. And my Canon 550D does not have an in-built transmitter to fire off-camera flashes. Which of the following will be suitable for my requirement? Or do you want to suggest anything else?
• Yongnuo Upgrade RF-603 II C1
• Yongnuo YN-622C Wireless TTL Flash Trigger
• YONGNUO YN-622C-KIT
• YONGNUO YN-622N-KIT
• YONGNUO RF 603C
• YONGNUO YN-622C-TX
Thanks in advance
