I'm a teacher looking to take videos of my test prep classes to stream online, and perhaps convert to DVD later on.

I would like to purchase a video camera with broadcast quality (or near) image and sound, but in an affordable price range (ideally around $1000, but I'd go up to $2000). My questions:

1. Because I'm shooting only indoors, with very little camera movement, can I get away with a less expensive model that still has great picture quality? Any recommendations for a good amateur-turning-pro model?

2. Is HD what gives a video camera that TV-like quality? Or can I get the same quality pic with a non-HD camera? I've tried some nice Canon HD cams, and was a bit surprised at how much they brought out the freckles on my skin -- I want TV quality, but would like to avoid clearer-than-life views of any blemishes I may have.

3. As I will be uploading these to my homepage, will HD vids have extremely large file sizes that I should avoid in favor of a non-HD camera? Again, I want high quality picture, but I want to be able to affordable upload my videos without paying an arm and a leg for hosting.

Thanks!
