I've ordered SB 900 but I want to buy a second flash that's quite inexpensive but good. I also want it to be compatible with Nikon's TTL system and usable as a slave. I was planning to buy Nissin Di622 Mark || but a friend of mine (photographer) told me it's not strong enough. What do you think?
Any other suggestions?
My budget is up to 180 dollars.
(I'm also planning to buy Nikon D800 in a few months)
