There is the very-much-finished (at least in terms of hardware) Kryoflux. Their entire goal is to create 100% accurate imaging that can recreate the original diskette to the last detail. They are there for Amiga and not far behind for C64. Some read capability currently exists for Apple (even for 800k diskettes - and in a standard PC 1.44M drive no less!).
My understanding is they started from the Cyclone20 and improved it. However it is not open source, is it? So I lost interest. Not because I'm a looney leftist - rather the opposite - but because I like tinkering and don't need to use the final device very much. The original code mostly works. Just there are occasional error while writing back "perfect" images of Amiga disks. And there is no special hardware - the Atmel ARM7 running at 57(?)MHz clock is fast enough to capture the raw flux transitions from the floppy with 40 ns resolution and send it to the PC via USB.
