I have the GoPro HD Hero 2 outdoors edition, this edition will come with a lot of what you need, like sticky mounts to mount to your helmet. You will need to get an SD card because GoPros do not come with them, i went on amazon and bought a 32 GB one, http://www.amazon.com/SanDisk-32GB-Flash-Memory-SDSDB-032G-B35/dp/B002G12OBO/ref=pd_cp_e_2 there's the link for that. 32 GB is the biggest it will take and i recommend getting that, because with that the battery will die before you run out of space. Another accessorie i suggest getting is a pole mount from www.gopole.com this is the classic mount for snowboarding, it allows you to film yourself or turn it around and film friends to make those nice edits. If you are debating between HD Hero and Hero 2 go with Hero 2, its a little more but its worth it for the quality of the video, I got mine discounted on amazon http://www.amazon.com/GoPro-HD-HERO2-Outdoor-Edition/dp/B005WY3TI4/ref=sr_1_1?ie=UTF8&qid=1346967661&sr=8-1&keywords=gopro+2
