I've been happily using CLS to control manual flash power on OCF. Looking at radio triggers all of the budget ones (RFs, Cactus, etc) require you to dial the power on the flash unit. I know the PW has that AC3 you can buy to control power from camera.

Are there any in between, I don't need TTL but I would like to control it all from camera if possible atm I still take many tries to get the power right, I know you light meter strobists there can set it up within 2 goes but I'm still a way off
