Hi Everyone, I have a question about off-camera lighting. I have read countless threads and all I seem to be doing is confusing myself more. My equipment: Canon 30D, 580 EXII and 430 EX My goal: off-camera lighting for small portrait set up that I can also take out and shoot action photos with flashes in random spots (don't have to see each other) questions: 1)If I want to shoot in both manual and Ettl mode, do I need to buy a pocket wizard? 2)If so, do I need to buy 1 tranceiver and two receivers? 3) Is there any other option than the pocket wizard? Those things are sooo expensive! Thanks!
