ShowZ has this guy in stock now for anyone interested in the KO route, and a Chinese video to accompany that --

The thing that surprises me the most about it is that they didn't also knock off the replacement head pieces that allowed the arms to tab in. I know from first hand that Data Clerk didn't include Cupola's replacements (but they were fully compatible in installation), but the doing the sides of the head seems like it would have been a simple piece to do.
I had traded up my Data Clerk when MT put Cupola on sale, but I wish that I had waited for TCP's Iron Will sale. I don't regret purchasing him at full price, but saving money is always great.
