Sorry, but the video camera of choice for MS is still th PV-500 with ectended battery life. $300 and up. However, some folks have had good luck using a good cell phone video with audio for short interaction videos. Avoid any video camera that is head mounted (hat or eye glasses) because when the subject moves even a little, you will move your head. This can result in a lot of rejected video becasue it begins to blur the picture just enough to make the viewer experience nausea.
