I'm pleased with Vuescan Pro and my Minolta Dimage Elite F-2900 scanner. The interface is more 'Windows XP' than 'Windows 10' but it works reliably and I see features /new scanners added regularly
Documentation leaves a bit to be desired, but Sascha Steinhoff's 'The Vuescan Bible' is an OK beginner's book (more tips are only available on the web).
Given the modest price, added features and lifetime updates, I think splurging for the pro version is the smart move...
