There are the various "camcorders" like the Flip thing, but I don't know if it's "true" high definition.
There are also digital still cameras with a video mode that'll give you high definition. Like the new Canon Power Shot that they say you can get on the internet for $140.
There's a $400 Panasonic digital camera, that'll give you high definition video, and you can set the aperture and focus while you do it. I assume that'll work. There are some point-and-shoot digital cameras where you can set the aperture and focus, but it makes no real difference because the chip is so small that everything is in focus anyway.
I've seen lovely video shot with digital SLRs that was very nice. With most camcorder, everything is in focus. The digital SLRs, they were able to get a nice shallow depth of field.
I heard that, with the Nikon digital cameras, (at least with the point-and-shoot ones) the sound is always out of synch on video mode.
There are more conventional camcorders.
There's the Panasonic three chip HD camcorder which they said somewhere you can get for about $900. But the site I looked at discussing this noted that the three chips make the picture only slightly better than the more affordable single chip HD camcorders sold by Sony and Canon. Be sure there's an external mic jack.
Aiptek makes several very inexpensive high definition camcorders. They have the great advantage of coming with external mic jacks.
