Can someone explain it to me like I'm a 3rd grader? I'm looking for radio triggers for my soon-to-be-bought 430exII but I'm scared of losing Canon's ETTL feature and I can't spend ~$450 on the new PocketWizards that allow me to keep this feature while synced wirelessly. I've looked for cheaper alternatives that allow TTL metering but I'm coming up dry. So I'm assuming that using the flash on manual with cheap Cactus triggers is the only option left. Problem is that I'm afraid this is going to be extremely annoying. Problem is that I don't understand how to do this. I've read how to do it but it just won't process in my brain.
