lot of choices, so I'm looking for advice on what to look out for.
For those playing along at home, the AIM-65 wants 5V at ~2A, and 24V at
~2.5A.
I don't know where to get one now, but my AIM came packaged with a
steel bottom, a plastic top, and a PSU that has "AIM65" in the part
number and that provides +24V. It looks like many other 1970s
open-frame switchers with a large 1/8" or 3/16" aluminum baseplate and
one or two power transistors, but unlike the others, it has more than
just +5, and +/-12V.
So at one point, someone was making 3"x4"x2" PSUs just for the AIM-65.
Unless you happened to run across some that someone has as a stash of
spares, I don't know where you'd find that exact model now, but it
does exist.

A lot of the old dot matrix printers had +5V and ~+24V supplies that would
work with minor adjustments (also good for 8" floppy drives); they usually
just end up being scrapped anyway.
