just be sure to get one that uses mini DV.
the guy in the store will tell you DVD or HDD is amazing and it will hold X-amount of hours etc, but that means you have to mess with the quality, and if you never get around to putting it on your pc, then theres nothing you can do. but with tapes, they can pile up over the years.
DVD is a bad idea, because the picture quality of dvd is reasonably poor in comparison to MINI DV, so if you buy a HD camera, but are recording on DVD, its pointless, its like recordiing a DVD to VHS, the quality is less.
I use Sony for work, but at a consumer level you cant go past panasonic, always great pics at reasonable price.
does that help?
