We are on the hunt for a GOPRO. For those who have them, what should we be looking for? And what should we avoid. After looking at the GOPRO site, there seems to be a big difference between models. So does one need all the capabilities and features of the higher end camera? I suspect, much like my phone, I”ll only use 5-6 of the 200 available features. Do we also need editing software? Thanks in advance.
