Really a tech question.

I'm thinking of putting some of my day game on youtube, does anyone have any experience or knowledge of using button cameras and microphones?

What sort of things should I be looking for? I understand resolution thats about it.

Not looking at spending huge amounts of dosh, can you get away with entry level equipment or will quality be compromised?

Is the video going to be viewable or will it be jerky and unwatchable?

Thanks
