The shutter on my (ex the Bay) second hand one started to be slowish, it was a quick and cheap repair (if you can find someone to do it, in my case an all rounder).
I don't find it the easiest camera to focus after the split image Mamiya RB 67 screen system (any tips welcome) Mine has just a ground glass--with a quite bright image--and the built in magnifying loupe and needs fairly good eyesight and a regard to zone focus. I loaned it to a friend who was unimpressed by the focus procedure.
That said as a slight downer, it does make good pictures, is very compact and light and impresses Japanese tourists in Sydney. I understand that candid street pics are facilitated because the photographer is not looking through the viewfinder at the (un) suspecting subject.
