Ah, so you're also watching that one on ebay with the bad column. Tempting at the €2.6k price, isn't it?
I'd certainly consider it for scientific shooting, where you can convert the channels to FITS format, and either interpolate, or shift-and-add with a BPM, to work around the bad column issue.
But for regular photography, I dunno. The corrective workflow might be a PITA. I'm not aware of RAW converters which can automatically handle that sort of problem; maybe RawTherapee can, since it's particularly good on properly calibrating images.
