not sure what type of "BEST" you are looking at...
I am planning to try and pick up an HD cam for my vacation soon. So I am looking at the consumer models from Sony and Canon, and maybe Sanyo and JVC or Panasonic?
They all use a variety of media to store HD, from DVD, Harddrive to even minidv.
Again, not sure what your "best" is. I am leaning towards the Sony models that use mini DVDs or the Harddrive model. No minidv for me.
