I'm getting into the idea of doing some studio-type photography, and am looking for an entry level but quality lighting kit. You know, couple of strobes, stands, umbrellas etc. I know next to nothing about it, therefore need your vast knowledge. It should be noted that I have a D40x and an SB-600. Neither of course has a flash sync. Is it worth going to quality [expensive] Pocket Wizard route, or what would you suggest?
