Hey Sebastian,
The cameras running CHDK did a great job for their price point. We never ran into any real problems with them, they are very stable. The only slight pain with point and shoots is the lack of a program, such as Smart Shooter, to automatically change cameras settings and download pictures.
After the project we bought the cameras for ended, we decided to take some of the profits and upgrade to DSLR's for more control and higher fidelity.
Thanks,
Corey
