There's quite a few companies that buy used industrial equipment. Just do some Google searches.
Downside is they only want to pay pennies on the dollar, but sometimes it's better to get something rather than nothing.
Good luck!
Or design a system around a drive you already have 😁
These were from a large hospital project that ended up morphing into other equipment.
