I have owned the 580EX for about a year now and have my 5th wedding shoot coming up on August 4. At my last wedding, I ran out of flash battery power and almost got myself in trouble. Many people here stated "You need to buy a CPE3". So, about 2 weeks ago, I did (haven't opened it yet). Well, last night, I read on the forums that there is a new 580EX II that offers a few nice features including better battery life and recharge times. My question is this: If it were you, would you:
A) Keep the 580EX and CPE3 and ignore the new 580 II
B) Sell the 580EX, return the CPE3, and buy the new 580 II and plenty of Eneloop batteries
C) Sell the 580EX, return the CPE3, buy 2 580 II (one for backup).
Thank you for your input.
