A good bet for the future is to get a Macintosh Classic, which can usually be picked up rather inexpensively. It has a 1.4MB floppy drive that also reads 800K disks. If you can find a 3.5" external floppy drive to go with it, you're even better off.

I have a Plus that I use on a regular basis (including for RetroChallenge). When I want to get files from it to the iBook or MacBook (which happens all the time when someone wants a report, term paper, etc e-mailed to them), I will save them on an 800K disk, start up the Classic with the external floppy drive, and copy the file to a 1.4MB disk. It can then be opened with TextEdit, Pages, etc on the MacBook.
