I need your help.
I have had a 430EX for about a year, thinking it would be all I need. Decided recently it's not, so I picked up a second hand 580EXII. Very happy with it, and have even taken some muck around shots with 580 as master and 430 as slave and like the possibilities.
Since I have been in trouble with my fiance lately for spending too much money on camera gear, I haven't told her about the new flash yet. I have just started using it and kind of hide the 430. So far, she hasn't noticed that the black flash on my camera is different at all. But I'm sure she will notice if there's two instead of one!
Anyway, my dilemma is this - who long do you think I should leave it until I buy another 580EXII 
I exaggerate her just a little. But seriously, she had used the 430 on my camera before, and this Saturday we were at a party and she used my camera with the 580 and didn't even notice the difference. I'll tell her soon. After the wedding. Might go into a camera shop alone on our honeymoon with the 430 hidden, wait in there a while, and walk out with it and say I got it for a bargain price from their discount bin or something.
