It may be even cheaper and more readily available to buy two blank ROM chips and burn them with the Plus ROM. Here's what to do:
-Buy two ROM chips on eBay (someone here can recommend a part number).
-Buy a cheap Willem ROM burner on eBay.
-Hook the ROM burner to a PC's parallel port & USB port.
-Insert LO ROM, burn with LO ROM image. Repeat with HI ROM. (This may require splitting a Mac Plus ROM file if it's just one file, we can help you with this.)
-Put these chips into your Mac 128k and safely store the originals.
It is LITERALLY that easy to make your own ROM chips. If you have destroyed a Mac with this ROM (Mac Plus, 128ke, 512ke), or if someone who has can vouch for you, maybe this could be considered a legal backup copy if you're overly concerned about that sort of thing.
800k drives can also be had from eBay.
