Are you sure that was the cintel and not the $40K Scanstation Archivist (a redesign of the Scanstation Personal)? It has options for warped film gates and HDR, but it will still be a “licensed” machine requiring servicing from Lasergraphics which is what would make it unsuitable for personal use unless you plan to cover the ongoing servicing costs somehow. From what I understand about the HDS+ it’s fully user-serviceable so you just buy replacement parts and do it yourself.
The cintel wasn’t designed with upgrades in mind. The slow data transfer speeds is why they have to do HDR in a 2-pass mode instead of one pass and that is probably what causes half of the HDR registration problems. If they’ve redesigned it it should be with a faster data link to the host computer so that future upgrades are possible without slowing the entire machine down (for example a 6K camera or an 8K camera with the same scanning speeds). It would probably take quite a bit of modification to any existing Cintel 1 or 2 in order to change over the data outputs, so I can’t see that as being a very viable option.
I’ll be great if they’ve made some advancements, but I’d be quite sceptical at the moment. They’ve had three years to fix the HDR registration issues in software and they’ve done nothing at all about it, let alone the hardware issues as well with it. Plus the sensor, even one of their distributors pre-release was speculating that there should be a 4.6K sensor upgrade:
And there are still no archive/warped-film gates available for it either.
