I have a lot of Pentax SLRs. ME Super, MX, KX, Km, but actually prefer my Spotmatic F, and used a few S1A's alongsideone for orofessional work, now I have a mint SV & meter alongside the F an an originl Sp and an SP 500, there is an S!a I boughtfor parts but fixed. The SV with an SMC Takumar f2 f55 & its meter was £10 just before the Pandemic hit, the seller (at a camera fair) had bought a huge job lot of cameras and after cherry picking what he wanted was just recovering his costs

That's the way to get bargains, it's not the first time.
