I would not waste my money on a miniDVD based camcorder. I like to edit - and I post stuff to the web at MySpace, YouTube and websites where much less compression is used. If someone GAVE me a DVD-based camcorder, I would recycle it be cause I would feel too guilty giving it to someone.
MiniDV tape based camcorders continue to provide the highest quality video image available and are affordable - as are the tapes. A Panasonic PV-GS320 (no external mic jack) or even a Canon ZR800 (has an external mic jack) would be a much better investment... but if you have no expectation to get the video into your computer for any particular reason, then it does not matter.
I have been using a Sony HDR-HC1 for almost 2 years. Before that is was a Canon Elura. I am currently looking at the Sony HVR-V1 or HVR-Z1, Canon XH A1 or Panasonic AG-HVX200. These cameras are very different than those you are evaluating. They will do everything you want - and much more... and they all have a couple of common items: They all do high definition and they all record to miniDV tape. That they all *can* record to an external hard drive is helpful, but a nice to have (external drive file format is like tape - not like the internal drive camcorders). The Panasonic also can record to P2 memory cards.
If I was in your shoes, I would probably be looking at the Canon ZR800 (to be fair, the PV-GS320, PV-GS85 and Sony HC96 are fine cameras too). Video is about 1/4 of the story... Audio, editing and lighting make up a big part of the important stuff. Of course, it helps to have a good story (even with family videos); characters/subjects willing to be filmed... but this is just my opinion...
