I have invested in Radio Poppers and have been using them for more than 18 months very successfully. I have an SU-800, 2 SB-800s, 2-SB-900s and 2 SBR200s. They are very reliable. I am not sure what Pocket Wizards will need to do to make me switch. But, right now, the poor PW/TTL/Canon experience says don't be an early adopter of their new PW/TTL/Nikon offering.
