Flash System for D800

Please let me know your impressions on the Nikon R1, Digi-slave 3200, Nissin MF-18, Alien ABR800, Ray Flash, or any other suggestion. What do I also need if I decide to go with a more simple system such as the Nikon SB 800?

I am looking for functionality and simplicity + quality + under $1000.00.

If I could use the system for portray as well, that would be a plus, but my main priority is Macro work.

Thank you so very much.
