I had a lomo cybersampler but the film advance mechanism spoilt after lending it to a friend. Prob the spring broke. The camera is known for poor quality control. It was a complete lemon even when still working. Some people are really mad with lomo becoz it hypes up the cameras and sells them at exhorbitant prices. That said, I still like toy cameras, but will not pay and arm and a leg for them anymore, and definitely will never buy anything lomo or from the lomo site.
Hope you have better luck with the Holga.
