Searching on ebay about 4:00 in the morning I saw some bloke had come across a whole pallet-load of Amiga internal drives and was selling them off cheap. Sorry I don't remember the link, but it was nostalgia-something-or-other. Try checking ebay.
Also I too have a ton of disks that have gone south on me. 10 years in my slightly damp basement was just too much for them. Sigh, that was some good stuff, too! Atleast I can look at the labels and remember, and hopefully download them from somewhere...
