Help - IIGS 5.25" floppy ??

[jchau@skynet.litc.lockheed.com (Jon Chau)]

Hi Apple IIGS users,
  I need some advice on purchasing a 5.25" floppy for my aunt's system.  
She already has a 3.5" drive, but was given a lot of educational software
on 5.25" disks.  I know her system is (ROM 01) and that her 3.5" is has
a 19 pin connector.  Do I need a specific 19 pin 5.25" drive from APPLE or
can a generic 19 pin floppy work?? (I assume she would daisy chain the 
drives together...)  

Thanks for any help - from an unknowlegable IIGS user,
