I use an Epson 3200 Perfection scanner which supposedly scans to, yep, 3200 DPI. I see no difference between 1600 and 3200 so I'll usually scan at 1600. I use Vuescan for control of all the scanning parameters and am happy with the output.
If I come across an image that I really want to do something with, like print large for example, then I'll just have a lab scan it on one of their high end machines. That didn't happen in 2020 but there's hope for 2021
Take a look
