I bought a V800 about 10 years ago for film scanning and it worked with modern computers. The quality was quite good as well; I wet-mounted my negatives and had pretty much no complaints with the quality. Speed was not amazing, of course.

I ended up with a flatbed and not a film scanner because I wanted to scan 4x5 negatives.

If I were being rational, I'd just get an A7R or Fuji's medium format DSLR for 90% of my photos and have 4x5" and larger negatives professionally scanned. For proofing, I always found taking a picture of the negative on a lightbox with my phone and inverting to be adequate. If you like the photo in that form, then you'll like the professional scan.
