As another option there's always this:
http://www.amiga.org/forums/showthread.php?t=62243I have one and it works great, it's what I used when I first got my 1.3 A500 to get it up & running with some games and other software, and then later create 3.1 setup disks when I began to expand my system. Now a'days if I want to transfer software over I just burn it to a rewritable CD with my PC and read it back on the Amiga, but when I was using this kit I had zero issues outside of when I'd use a bad (20+ years old) floppy disk.
*Side note - I actually feel pretty bad for the guy selling this kit after the bashing he took in that thread. Can't speak for the other guy's issues but it worked great for me, so just passing along a recommendation.
