Are you definitely set on a dedicated scanner? I bought an Epson V550 and sold it again to commit to DSLR scanning. The results with my Nikon D850 are just so much better it's incredible. In terms of workflow speed, I think they are comparable. A used Nikon D800 with a macro lens will also set you back less than a decent film scanner.
Here is a great article about the workflow, and Nate's Lightroom Plugin for the conversion is fantastic:

Don't worry, you don't need a Lightroom subscription, buying an old stand-alone license for Lightroom 6 is what I use as well.
I use a Lomography film holder with this setup, but I am about to replace that with a custom built film holder to process an entire roll in one go. I used to have some slight problems with dust (see below), but all those problems were also resolved after learning with my first few rolls of film.

Here is a scan of one of my images (scanned at less than half the possible resolution and compressed for upload) and a detail crop:

Overall, the setup is comparable in terms of cost with a flatbed scanning workflow, but in my opinion is much more flexible in terms of film formats. Also, I am icnredibly happy with the results, as the colours also come out a lot nicer than on the Epson in my opinion.
