I am trying to find out as much as I can about pocket wizards and what I would need to get for an off camera flash setup. Is there something less expensive that works as well? I am not Joe McNally and will not end up with twenty or thirty flashes in use at one time. I am mainly interested in starting out with one flash and may work up to between One, two or three latter. I already own the Nikon SB600, SB800, and SB900 flashes. Any guidance, suggestion, tips or info would be greatly appreciated. Grandpaw
