I'm guessing that you have many Amigas and trading one is no big deal. I can understand wanting to collect samples of the early pioneering computers before they are all recycled.
I have one Apple IIc left and some software for it for my museum. After playing with it for 10 minutes (or less), it was clear that any Amiga is far more capable, flexable, updatable, fascinating. If I had to settle on just one old machine, it would not be an Apple II.
OTOH, I'm glad to have found a good sample of Apple II and will probably pull it out again in few years.
Another thought, if you just want to run your A2 software. A Mac LCIII expanded with an A2 card and 5.25 floppy drive works well. You can also preserve your floppy based stuff on a hard drive. A LCIII (or Quadra 605, Performa 475) is an interesting computer in it's own right. You may even be able to move files to CD rom.
