I'm about to buy the Go Pro Hero 2 and I will mainly be using it on a Skateboard, Snowboard, ATV and for time lapse driving videos. Which Hero2 model / accessories should I buy and I was wondering what SD card(s) I would need and what setting to use to make a 24-28 hour road trip video. I don't care if its not in 1080p and can even be in VGA although if possible I would like somewhat good quality during the road trip video's. Also I will have my laptop during the road trip and can always stop and transfer the videos onto the laptop if needed to clear space on the camera, although I would rather not stop more than 3-4 times to do so. Also will I be able to charge it with my car adapter or does it take batteries that I will have to frequently change? If so how many / what type of batteries will I need for 24-28 hours of use? Any other helpful information / accessories I should get for a 24-28 hour time lapse driving video please let me know, thanks!
