I _think_ the older Microsoft "Bus Mouse" was a quadrature device. I was

Yes it was. As were the ST and Amiga mice [1], the Apple Mac mouse used
on machiens before ADB, the PERQ 3A mouse [2],the Depraz 83/P mouse (used
on the Qhitechapel MG1) and many, many, others.
The are probably planty of them around out there if you know where to
look, but getting _new_ ones is probably impssible now.
[1] About 15 years ago or more, Maplin (a major hobbyist component
supplier over here, at least back then) sold clone mice for the ST and
Amiga. One had 2 buttons, the other had 3, and they ahd differnet wiring
to the DE9 conenctor. I converted several of them to use with other
machines by cutting off the moulded connector and soldering the wires to
whatever conenctor I needed for the machine I was working on. No, Maplin
do not still sell those.
[2] But anyone who raids a PERQ 3A (==AGW3300) for parts is goign to be
LARTed. That said, I did once find a brnad-new-in-box PERQ 3A keyboard at
a radio rally...

For
anyone who doesn't know what these look like -- they're usually
branded either Logitech or CPC, and have a nine-pin Mini-DIN plug on the
Quadrature-output mice are getting hard to find now, and many of my
machiens depend on them, so I am keeping all I have ;-(.
