I just bought a Filmfabriek HDS+ scanner (picking it up in January). It’s 4K, and the camera can be repositioned. Plus it has a wet gate feature that eliminates many of the vertical lines on older prints. It is $10K more than the Cintel scanner, but you’ve already pointed out why it’s not a good buy.
The Cintel scanner was on my list of scanner options, but the fixed camera + the use of a sprocket gear guaranteed that I would never buy this scanner. (I have a lot of old, shrunken film that would get mauled by a sprocket-based scanner.)
