720K media is pretty easy to get as well, I bought 100 "used" disks from 
floppydisk.com, and it is hard to tell they have ever been used and I 
have not had any problems with them.  I also bought a lot on eBay that 
where previously used on an Amiga that majority of them where OK and the 
where a mix of single and double sided media.

Based on what I have read, I think that should let my A model use the newer 9122C drive, and other drives using either the Amigo or SS-80 protocols.

If I had easy access to lots of 3.5” DD media, then I would consider getting one of the more plentiful (?) other 3.5” HPIB floppy drives.
