I've been pining over the mac-daddy Sekonic 758 for a while. I just havent run into a situation where I absolutely, undeniably NEED that meter. It sure would make my life easier, and I think I will give in one day, but I just grab a spare 35mm with a spot meter function and base exposures from there. For flash and incident I have perpetually borrowed a minolta III from a friend.
[Perpetually Borrowed is not = to stealing, its the same guy I shoot weddings with and he has more meters than he knows what to do with, and condoned me using it]
But from all reports and my drooling over the fancy Sekonic, I'de go with the 758. It fits the billl.
All the best.
