Hey, I'm looking to get a flash lighting kit to be used both for weddings and studio work. I currently own an SB-900, SB-600, and 2 Vivitar 285HV flashes. 3 Umbrella's (2 shoot through, 1 reflector) and a softbox. These are doing a great job for my general purpose lighting but they will not give me the recycle times nor the battery life (they also might lack the power) that I will require. The question is what kit would you buy with $1000. Your input is appreciated, thanks.
