I like 5 because of the snow camo, and it looks kinda cool.
You know you should totally get a gopro hd camera: it's a mini video camera you can mount on your helmet, or even attach it to your gun and you can get some awesome footage off it in high res.
I bought one a while back and it's all the rage when making sports videos, and alot of fun to play with.
Here's some footage I took while playing around with it:
There's a few other clips up there too if you browse, or go to the actual website for the Gopro and check out some of the crazy footage they take. It's waterproof too [as you may see by the clip of me 'drowning' my friend in the bath on my vimeo].
