I got myself a kryoflux about a year ago, because I also had a bunch of corrupted disks. I was actually able to recover almost all of them..... what I found was that different drives would have different failed sectors, so I bought like 5-6 different floppy drives, and would scan the same disk with all of them. I could then patch together the working sectors from each drive to get a full image.

Kryoflux is pretty amazing
