I'm thinking about buying a flash for my D90. The obvious choices are SB600 and SB900.
However, I don't shoot with flash very often, so I'm looking to save cash. The price of the SB900 is more than a little off-putting for my needs.
Both Nissin (Di866) and Metz (58 AF-1) seem to have specs not far off the SB900 but at prices nearer to the SB600.
Anyone any experience or views on third party units compared to Nikon's own?
Economise on price
Economise on size/weight
Bounce head, ideally with a secondary 'fill-flash'
Option of fully automatic control, ideally via camera
Not bothered about multi flash setups
