He's on the map, looks serious and says he uses special equipment and takes a long time to develop his presets. I still think $89 is just far too greedy, but can't blame anyone for trying. I'm also suspicious of the video he's posted - but I guess you'd have to send him the money to see for yourself if it's legit or how it's done.
I would prefer if the video showed "out of the box" compared to the new profile. I just spent an afternoon with color charts and my broadcast monitor adjusting my XF300 profile. Great to be able to adjust the camera so much.
