Thanks for all the replies.  My nephew, who is a tech geek, talked me in a GoPro3 black edition with battery pack and LCD pack ( + suction mount for the JK).  He uses two GoPro's for 3D diving film.  Headed to town tomorrow and if the wife doesn't watch to close will have one tomorrow.  I will probably have a steep learning curve but hope to be filming by Jeepfest.
