I was very pleased with the Garmin Virb I tried this past weekend but didn't find time to really play with it. I got the base model with no Wifi and GPS so there wasn't much else to play with anyways; I also got the remote that has a feedback LED (flashes red while recording) so no guessing as to whether or not you are live:

I will be sending it back to get the Garmin Virb Elite for $37 more that has built in wifi and GPS. It has GPS based recording profiles so I don't have to manually hit the record button, and can also overlay data from external sensors if you want to mess with that. Going for the auto record and wifi as the SD card is inside the unit behind the battery so I'd like to avoid having to take it apart to get data every time.
