I have a Nikon D50 so no commander mode. I want to be able to wirelessly control one or more flashes. I've been looking into getting a Pocket-Wizard Plus II but then I found out the Nikon SB-800 flash can act as a commander. I currently have a Nikon SB-600 flash that I can use has a wireless slave flash but I need something to control it. Is the Nikon SB-800 or the Pocket-Wizard Plus II a better choice to control a few SB-600 flashes?
