Cameras that are easily serviced would be a smarter choice. I decided on all mechanical for its simplicity and lack of electronics. I once craved a Contax 645 for my professional shoots, but service and parts are scarce in the industry even though the lenses are amazing. Understanding the zone system and metering handheld will forgo any need for electronics. Eventually, you won't need a meter at all except for determining long exposures at various apertures and reciprocity.
