Hum,
my ungamely solution (er, once you`ve fitted or fixed a new amiga floppy)would be to connect the amiga to the pc via a lap-link cable and burn all your floppys to CDROM...
Er, of course, you would have to fit a CD to the amiga to play them....(which is very easy)
i imagine the burned CDs will last longer than the new floppys...
