Where to get replacement mouse cords?

[Computolio]

I've got something like 6 or 7 Logitech Bus mice in a box somewhere, all missing their cords. Any idea where I could get new ones? I can't seem to find any 9-wire cable that has anywhere near the same thickness as the original cords. I can't get this type of non-standard cable locally, and I can't find it online either.

Has anyone else had better luck?

Another question: Where would I get low-profile male DB-9 connectors, like the ones used on Commodore mice?

    Unfortunately, most Logitech Bus mice have 3 buttons. The Maplin stuff doesn't look like it's thin enough for mouse use (although it may work for gamepads), but it does seem pretty close. Too bad they don't ship to the US.

    I'd need something more like 4 or 5 mm in diameter.
