Minolta Auto-cord, purchased new, shutter failed after about 2 yrs. The repair cost quoted at local camera stores was almost the price of the camera so traded it in. Nikon FG, purchase used, still use in on the one manual speed. Had a few others that purchased used and needed CLA, such as Rollie SL66, and yes, had it done and kept it for awhile. I worry about my Minox GT, still works though.
