What safe and free camera product would you*

[~Axis~]

As far as free ones, you'll probably want to use Fraps or Gamecam if you're recording games.
I personally use Camtasia, but it isn't free...

I thought you needed to buy them to get the full functionality. The demo versions of both Fraps and Gamecam have a 30 second recording time limit. Gamecam also doesn't record sounds until you register.
