hi,
Here is a small company that sells new fdd for use with amiga, the floppys works great, i have 3 of this ones, one on my 500, 1200 and on one of my external floppys. The only bad thing is that for use them on amiga 500 600 or 1200 u have to cut a peace of the buton, or cut a small pice of the chasis or use it out of the amiga, but come on, everybody can make a small and simple modification, the very good thing is this floppys works great and you will be able to load all your amiga stuff from floppys, works 100%
cheers
