Thanks so much! I was (still am) seriously considering the RadioPopper JrX system because being able to control the output of my Canon Speedlites at the camera is very appealing to me. I know for a fact that they will not "wake" a sleeping Speedlite because I emailed their customer support. This is not a deal breaker but I'd really like to have it. What I don't get is that the RF-602s on eBay say that they will wake a sleeping flash gun. It surprises me that not all of the big players have this built in to their systems. Anyway, the Flex system from PW is about three timesthe cost of the RadioPopper system but it's about 10 times as robust! Having both the option for wireless E-TTL and manual controls all on the camera (via the yet to be released ZoneController as I have no interest in mounting a 580 to my camera to execute these functions) is truly amazing...on top of the countless other features that set this system apart from the others.Originally Posted by peety3
