You can pick up a SB800 from B&H Photo's in NY, USA for about AU$330-350 including postage. Very good flash unit, but doesn't do the same as a ring flash. The sigma unit is better suited to macro as is the macro system by Nikon. I use a flash on a circular rail now as I can also mount the SB800 forward of the camera this way for telephoto. It also lets me move it closer for macro too.
I'd be looking at the SB800 (or new SB900) first over the ring flash unless you are going to do a lot of macro work. Also remember the SB800 will work remote from the camera (even on a D80 I believe)
