I'm so confused. I don't know whether it's best to purchase an sb-400 or wait to save up and purchase an sb-600. I'm new to photography, and I want something that would be versatile and worth my money. I built this beauty dish and was wondering if an sb-400 would work for it? or an sb-600?

I have read plenty of information on both items, but I'm still confused and not satisfy. I think I need more of a personal experience opinion to help me on this. I just want to make sure I'm doing the right thing. So if I can get your personal opinion on either one of the items, then that would help me a lot!

Thank you guys!
