What's the general feeling among members here on auto - threading projectors?. There seems to be quite a lot of opposition to them in other forums, with someone describing them as 'autoshredders'. I suppose different manufacturers had their own systems. I find manual lacing a bit tricky sometimes, and waited two years after buying some films until I got an auto-threader before I would show them. I never had any problems with my Eumig 810D, and likewise with my Bell and Howell 655.
In Super 8, Chinon use to have a bad reputation for perforation damage, and in 16mm Singer-Graflex appears to be the same.
