I am no expert, but I would think the Mini DV format is probably more to your needs. The last I looked, the mini DVD cameras were about $500. Also, the resolution of the picture was less than a Mini DV and the discs are not reusable. I would expect your son will download the video to a PC and edit the footage anyway, then burn it on a DVD from there. It is very easy to download from Mini DV tape via firewire for editing with the right software. As for zoom, the more powerful the zoom, the more still you must hold the camera, so that has its drawbacks. (I would bet the hunter here from the 1000 yard Pennsylvannia club would be a good person to ask, as he posts his videos here).
When I bought my Mini DV last year I found a website (CNET or something like that) that rated all of the current models. I based my purchase on picture quality and resolution as all other features are usually the same (or close) for each camera.
Hope this helps...
