For SB-700 has been here a lot said, I do not have to repeat. I own next to the SB-700 also the SB-900, the I but much less frequently used. The reason is quite simple: 99% of my needs are met by the SB-700, but in my overfull Fototasche requires this massively less space and especially overheated this in continuous use much less quickly than the SB-900, in which, unfortunately, regularly happens. The quality is absolutely at the top two.
