I would give thumbs up for the Pentax Spotamatic and the Praktica LTL series. I have a Carl Zeiss Ultron 50mm f1.8 from my old Zeiss Icarex 35S TM Pro camera I used decades ago. The camera has issues, but I want to use the lens (with film, I have also adapted it to my digital). I picked up an early Spotmatic SP for $16 and a Prakitca LTL3 for $20 (plus two generic lenses, one that might be salvageable). The Praktica has light leaks which I am working to repair. I have used the Pentax and it is fine. Neither camera seems to have a functioning meter, so I use a handheld meter.
I actually like the feel of the Praktica LTL3 (weight, grip shutter release location, winder action, shutter feel), but given the light leak, I am using the Pentax for now. The Pentax is a bit clunky (like my Zeiss Icarex), but it is also similarly solid.
