8mm film scanners are so common they're available at Walmart.
There are lots of DIY film scanners described on Youtube. They don't have to run fast and they don't need a pull-down mechanism, so they're simple devices.
Then again, those scanners didn't have sufficient resolution for 8mm. I think the LS-2000 was something like 2700 DPI... which would only yield 800 or so pixels across. So it would have also needed an additional lens.
