I work for a newspaper that is starting to get into video. Our corporate mothership has a list of video equipment that each newspaper should purchase. We have purchased a couple of Sony HVRA1U HDV cameras @ $1900 each. They also recommend a HVRM25U digital recording deck at a price of $2700. Why wouldn't I just purchase an extra camera to use to capture video, especially since the camera is much cheaper than the deck? What does the extra $800 buy me if I purchase the deck?
