I have a go pro 2 and the video is all you need unless what you have seen does not meet your expectations, which I could not imagine. The problem is sharing your video at the 1080 w/30 frames per second creates a huge file that is too difficult to upload/download to utube. Once you edit them down the quality is no as impressive which is typical.
