My favourite video camera isn't the expensive video camera I own. It is the free video camera on the iPhone I already own.
The video camera on Android phones are often very good as well. So are the cameras on iPads and other tablets.
If you don't own one of these then borrow on from a friend, ask for their old phone when they replace it (or buy one online, I know it isn't free but you cna pick up phones at very low cost).
