I like my Go Pro Hero, video quality is amazing.
However there is a downside. With all the extras I've needed to buy, spare battery (batt life approx 2 hours), rear view screen and remote capability a £200+ camera is now a £500+ camera
Looking at the Drift and reading up on it, I'd say go for that. Very similar in quality and most features incorporated already.
I think the 15min play memory feature is really cool.
If I'd have known about the Drift before purchasing the GoPro, I would have probably opted for that.
For decent cheapish camera, look at the Muvi range. Decent enough but you get what you pay for with regards to quality.
