I am running the IIeX, when my upgrade kit arrives I will be running the IIIeX.

The others that will work with the AI light, but cost a lot less are the II ($300) and Light II ($283), you cannot upgrade these models.
I agree that the Profi has serious controllability, but also feel that it is more than most people may need/want. All I'm saying that, as far as light fixtures go, this one is pretty advanced in what it can do without the Profi.

When do you get your III? My upgrade kit has shipped already ...
