The 335 is a pretty good one with a glass lens. I believe it has a plastic body, if I am reading correctly, and a viewfinder that does not fold down, but functionally it is as good as any, probably, until you get into the ones with the decent lenses, like the 180 or 195 (which get pretty expensive on eBay). The film is probably a goner, I think 108 was replaced by other films quite some time ago. You can use the Fuji pack films with the camera just fine, however.
