Thanks, me too. I have a collection of toy give-a-way 50mm "optical" lens cameras, but found that they are made so flimsy that when you rewind the camera you are likely to break the reel - way too lightweight and cheap. This is my fix for that - auto rewind and advance. No more risking breaking the camera just to rewind the film AND I can still get those lovely optical lens photos. Not to mention, now I have plastic chrome!
You can find these on ebay all the time, but not all of them have plastic chrome.
Wow, usually all they do on the "scameras" is to apply the Canon sticker. I had one years ago... came with a magazine subscription... thought I really had something until I took it to the camera shop... their laughter was memorable.
