Might as well get a $20 SJ4000 from Ebay [1] that can do most of what a GoPro can do...

I have no use for actions cams and am not an expert in any way, but the quality of that $20 camera looks amazing, in some scenes it actually looks sharper and better than the GoPro that costs 5x as much.
Given it was $50, and the shots I was able to pull off the memory card were great, I am not too upset. However, caveat emptor.
This happened because the GoPro probably records interlaced footage, which didn't get properly deinterlaced by the video-creator's software. Basically, the GoPro didn't get a fair trial.
That said, the SJ4000 footage has a decent quality, and I'm all for capable competition.
