Don't use one myself, but you might go to a website called OliviaTech.com. Olivia has reviews of all types of camera & video equipment. She makes her living as a photog. and cinematographer, and has access to a lot of equipment, some of it before it even hits the market. You should go to her website, and search for the GoPro. I've found her reviews to be factual, and unbiased. Scroll through her website, and you'll also find a lot of "tips & tricks" that are useful.
