>>4277194If you want a pentax, I'd say buy a ricoh. I have only had bad luck with more than a dozen pentax film cameras; if the mirror's not hanging up or falling out, then the takeup spool is slipping and giving overlapping frames, and don't get me started on the e-waste-tier MZ-xx line.
Ricoh's were the off-brand in pentax k-mount, but they seem to be much more durable.
I have an XR-P and an XRX3PF that are both nice. KR10's are more common and feel cheaper, but again all seem to work.
If your options are more open, then I simply recommend newer Canon EOS cameras, they aren't as hipster looking, but they almost all work with a new battery, they're wildly more sophisticated than old mf models and they're cheap as dirt. You can walk into any camera store and buy a brand new 50mm lense for one for less than vintage sets are being offered for too.
