I've run Hero cam for a while and recently got the DVR 295 HD cam system by adrenaline systems. The quality is great and it's a lot easier to mount and get special shots. The small bullet cam fits anywhere making it really easy to get some specialty shots (even mounted on poles etc)
What i like the most is I can view my footage on the screen without having to wait to connect to my laptop: Check it out at :
