Another SB-800/600 or Vivitar 285???

Hi,

I have a model coming this weekend to do some shots. It is the first time that I will try a studio kind of setup. Normally I do these outside.

I have 2 SB-800, 2 Lightstands, 2 Umbrella's, 1 Reflector

A white background and a black background. I was planning using the white background for Hi-Key shots.

But the problem is that I will need a 3rd flash for the background.

I thought that it would be nice to have a 3rd flash to use as a hair light or as a background light.

The question is should I get a Nikon (SB-800 or 600) or just a vivitar 285. I would say that the Vivitar 285 is enough but I love the possibility of controlling all flashes through the master + iTTL all wireless.

What would you do?

The other question is if I decide for Nikon which one to take. I prefer the SB-800 because they have more power and I believe you can never have enough power.

Please advise!

Tim
