i have the pentax k1000 that was my first 35mm, purchased for $50 back in about 1981 from a local ( now bankrupt ) department store.
still use it from time to time, its a great camera ! i also have a M E super and use that from time to time, but to be honest i almost prefer the k1000
solid and works perfectly. it has a shutter dial, and the lens has an aperture dial, not really sure what else a camera is supposed to have if it is a basic camera ..
i expose tintypes ( ferrotypes ) in it as well as paper negatives .. it is STILL ( after all these years ) one of the cameras i go-to ..
but then again i use box cameras, 4x5 box cameras/ falling plate cameras, self made lumen print cameras .. and don't mind low ( really low ) tech ..
i guessi have to say YMMV
