although I use a go pro for a lot of filming, this muvi is also a great little unit, much cheaper, but as good as, if not better, as it has a viewing screen on back, plus remote control for video or pictures

although another action camera that's getting good reviews is the SJ1000, basically a chinese import, but just look at what you get

and for the price, you could buy two, if your into editing, its always good to mix up camera shots, this video was taken using a go pro and a couple of extra action cams, not my editing, but our friend lewis that helps out,
