I didn't want to shell out all the money for a Hero, so I bought one of these tiny cameras for my Phantom: http://www.hobbypartz.com/86p-988-dice-minicam.html. The picture's fine, but the battery life is DISMAL. Tonight it died after only one minute and eight seconds! Has anyone else tried to use this thing? I'm thinking about returning it. Regardless, my question is this: what is a good alternative camera that doesn't cost as much as the quad itself?
