A couple of things worth noting:
The Canon EF-M shares its name with the lens mount for the newer canon digital cameras, so that can be a bit confusing / frustrating. It was also technically never branded as an EOS camera, due to its inexpensive manual focus nature. And also, like many other cameras of the era, it takes photo batteries which may not be the easiest to find.
EDIT: If you are interested in flash photography, this does not support the Canon TTL standard of the time, but had its own dedicated flash unit, which is not the easiest to find.
