Michael: I read your post and compared the Lisco and Fidlity holders side by side. To my surprise, the are both marked as being made in Sun Valley, Calif. and carry the same U.S. patent number. The only difference is a different pattern around the film chamber. Otherwise, they are identical to the smallest measurement. I have several of both and have been well satisfied with both. One problem to watch for with plastic holders...the bar across the top where the slide goes in can warp enough to prevent the holder from seating tightly against the camera back. I have three that are unuasable because of this fault.

Regards,
