POV Vio 1.5
I haven't used one but I've heard good things about the PIO Vio 1.5 (google it). Two attractive features for me are:
- uses 4 x AA batteries (2.5 hrs/alkaline, 5 hrs/lithium)
- A "loop mode" where the camera will film for a user set period of time and then erase and start over again UNLESS the user tags the clip in which case it gets saved. This saves memory and simplifies the editing process later.
You can find reviews for this and other cameras on Youtube...
