I normally view 35mm slides directly with an old Pana-Vue Bi-lens and consider this the best way to see slides. But it doesn't work for a group. I have an old Leitz projector where the carrier holds two slides, that alternately (and literally) slide into the light path. This is cumbersome for anything more than a few slides.
I'm looking for something fairly small (not much bigger than the Leitz) but that can hold a stack of slides (at least 38 to get a full roll). My brother has an Kodak Carousel that I have avoided asking him for because it is simply huge. What options would folks recommend?
