I have a Quantum T5D-R in very good working condition. It includes removable dome and flat diffuser (not shown). This thing is really amazing shooting bare bulb in a large room. I have replaced it and no longer use it so off it goes.
I also have the Quantum D23w-R TTL adaptor for Canon DSLRs.
I am also including the Pocket Wizard adaptor 3.5mm cable for this flash.
It all works great together.
D23w-R TTL Adaptor $25
Buy the entire kit for $115 Paypaled and shipped.
