Obviously don't know what specific camcorder they used, but the pics look a lot like mine, bought earlier in 2001 which came out in 2000 or so -- a Sony TRV-20, a decent 1 CCD camcorder. $1200 or so new at the time. In the daylight, the differences blur between cameras.
Not cheap but probably not too fancy.
Not cheap, but typical of what you get with a digital minicam. The "edit" is an in-camera dissolve.
