Cool footage, Desmond! I stumbled upon the GoPro cameras while doing some research for my work. I ended up buying 5 Hero 3 Black cameras back in November 2012 as they were just rolling out. These were my first GoPros and I can’t speak to the earlier models. As for the Hero 3 Black, the image quality is superior to the others, it has a faster frame rate, and it has built in wi-fi that you can control with the included remote control.
The Hero 3 Black came out a bit prematurely and there were some bugs that they are still trying to iron out. These mostly have to do with battery/external power and wi-fi issues. Other than these, this is a kick-ass camera.
I highly recommend for those reading this thread to look into Wasabi GoPro batteries. They are third party and are MUCH cheaper (and some would say perform better) than those from GoPro. I’d also suggest checking out YouTube to see what others are doing with their GoPro cameras. A favorite channel of mine is this one: http://www.youtube.com/user/micbergsma
