My son has the Drift camera, it works well and is handy with the screen, its even hit the deck once in a skatepark and survived so its worth looking at for sure. His has not much internal memory is the only thing, but it can be used as a hand held as well. I have a Go Pro HD and the pictures are excellent with it, the battery lasts for ages and its brilliant outside as well as inside. Its failing is its lack of a screen, you can get one that clips on but it adds more cost and they are not cheap to start off with.
If you know anyone going to the states get them to get you one there, I got the motorsports edition with the suction mount, other stick on mounts, extra battery and all the leads you need for $300 last July, bet they have came down more now as there is a newer model out.
