I have read many forums regarding the best flash for a D90 and get varying answers but I am still lost to which flash should I purchase. Some peoples say that the SB-800 was what they could afford and it works fine, and thats good I accept those comments, some say the SB-600 is all I need, again good and thanks. A lot of peoples say no the SB-900 is rediculously priced, hey isn't everything now days haha...but thats also fine I have appreciated all the comments. But $$$ aside, what differences am I REALISTICALLY going to see between all these 3 flash systems on my D90. Is it worth paying the extra few bucks and getting a SB-900? I have absolutely no idea how to set it up remotely off camera, not having one to play around with doesnt help I guess...but is it easy enough to work out? Cheers, and keep up the good work evveryone, I love reading these forums.....thanks in advance!
