I'm using an Eyetech EZDF0 PC floppy adaptor on my Amiga 1200 at the moment. It works beautiful.
I can recommend it to extend the life of a floppy based miggy.
They are a little on the expensive side though.. The adaptor alone costs $40 here in Australia

not good if you are replacing 2 or 3 floppy's

Good Luck..
