This one would be much faster than the plustek though, if they keep their promises. I use a 8200. It takes more than 1 hour to scan a 36 frame color negative with dust removal on, and it requires constant manual input. Pushing the holder to the next frame, unloading and loading the holder, etc.

It's fine, sure. For the price I paid for it and the image quality I'm getting, I have no complaints. On the other hand, a new device that can cut the time down to 5 mins with modern software support (silverfast is kind of dated and VueScan will run you another 100), while priced at 1000 EUR, is not cheap, but also not that unreasonable tbh.

For a studio or a professional - sure. For me, an amateur, who simply does film photography for his own amusement, it makes no sense. I also use standing development process that takes around 40 mins. So the speed is irrelevant for me.
