I emailed Mark Hama last night to get an estimate on a clean and calibrate for a Yashicat Mat 124 and a Rolleiflex MX-EVS. He emailed me this morning and the estimate for the yashicamat is $145 and the Rollei is $195. I can justify the Rollei but the Yashicamat seems a little high. I know he does incredible work so I am considering it. They are both in great shape, but the shutter speeds have become slow naturally over time and I just want them overhauled. What do you think?
