But, take for instance the reflecta ProScan 10T or the RPS 10M. Both
takes 7 minutes for a single shot! Yes, at 10000dpi.

no. it's 'effectively 4100 ppi', apparently inflating the true
resolution for marketing purposes, to fool the masses.

The Reflecta ProScan 10T is the top recommendation in the middle
price field for film scanners at the moment. It scans with a nominal
resolution of 5000 ppi and achieves effectively 4100 ppi.

As you can read in our test report, too, the image quality is rather
bad, if the scanner is operated with the manufacturer's scan software
CyberView. You will get very good scans only if you use the
SilverFast scan-software.

it needs third party software, which is even more money.
