My first SLR was (and still is) a Sears 1000MXB, M42 mount, I believe the Mamiya version. Still works fine after 33 years, the meter is still working if I bother to put a battery in it. Usually I sunny 16 it and get good results. Mine came with the 1.4 lens, it's the black body. A lot of film has gone through that camera and it should well for any beginning photographer.
Funny, I copied off a description of Sunny 16 for my daughter when she was running around with my camera. She nabbed it and said, " Why didn't you give this to me before?" Back off out the door she went. She dosn't like the light meter on my camera (yet). I did tell her they come in handy!
