I'm on the 600EX-RTs Chuck (just got my 5th one). LOVE them. I would get the ST-E3 IF they had the AF assist. They are worth every penny IMO. No more worrying and lugging around triggers, receivers, batteries, sleeves and adapters. For the most part, I just set the flash up, select the group and start working on dialing the settings.
