I have not looked for a specific travel case, but unless you are being really rough with it I would say a padded envelope or a generic small case would do it. It's pretty sturdy. I take it to to the office sometimes and just put it in one of the pockets of my laptop case. Also, for extra protection against scratches I never removed the clear plastic film that comes over the screen. Except for the red ""pull here"" tab, you can't tell it's there.

You can use that for that too. I make videos with it and am satisfied. Sometimes the ring is reflected, depending on the surface. 

I don't know the exact size but it even fits 12-13 year old kids. 

yes, however for added stability you should add counter weight at the bottom.
