In the manual focus era, I mostly used an A-1. But I also had a more obscure model (AT-1 maybe?) that had a match needle meter. That was a very intuitive way to evaluate exposure quickly, without needing to read or interpret any numbers.
All Canons of that era of can suffer from shutter drag though. You'd want to buy from a reputable source that would either know not to sell a camera that was dragging, or would be willing to take it back.
Or, get an autofocus body that takes your EOS lenses, like an EOS-1 or A2E or something.
