You can make one for $15 (plus shipping). No ordering custom boards, no fiddly surface mount assembly, and no fuss: nineteen simpler solder joints and you’re done. The hardware consists of a single, commodity part with a floppy drive connector soldered onto it. (Although not all of these are supported yet.

It allows you to use a conventional PC drive to accept Amiga disks, CLV Macintosh disks, bizarre 128-sector CP/M disks, and other weird and bizarre formats.

The Flu圎ngine is a very cheap USB floppy disk interface capable of reading and writing exotic non-PC floppy disk formats. If you want something more flexible than a USB floppy drive, but barely more expensive, and you're OK with beginner-level through-hole soldering and a command-line interface on the reading/writing tool, take a look at the Flu圎ngine.
