I've been considering a GoPro since they came out... still don't have one. Seems like every 'upgrade' there is a furor about whether it's better than the last one or not.
I'll tell you something 'aggravating'. I have a $2,500 camcorder. This year I wanted a second angle, my son-in-law would take the video, so I got online and found a 'refurbished' cheapo... but still HD... for I think it was $175. It takes better quality video than my $2,500 camcorder.
I'm not kidding... it doesn't have the 'zoom' ability but just for quality it blows my expensive camcorder away. - JamesJM
