Cameras & Camcorders

[batsheva]

We purchased 3 Sony Bloggie TS20.  

ON the box it's says 4 hours of recording, but the fine print in the manual says - continuous recording of movies is possible for approximately 29 minutes.  also recording stops automatically to prevent the file size from exceeding 2 GB.     

I need the cameras to video sessions of 45-50 minutes each.

Does anyone have suggestion of some other camera with will do?   (same type as this, small, sleek and simple)

Thanks
