the 100 body is the one i have been using, its just fine, the 200 body has a bent focus knob, does not affect usage but annoys me, 90mm #1 needs a cla, 90mm #2 aperture is broke, 60mm lens works perfect but the viewfinder has a little haze, i never used the external viewfinder tho. The 135 lens has a light leak, the rest of the lens is perfect. Back #1 works good but the film bunches up on once side of the take up spool, back #2 has bad frame spacing, back #3 the pressure plate has issues and have never used by me.
