Here is a pdf document that you can view, download, and share. It compares seven video cameras from $200 and less.
Feel free to use this short link: http://bit.ly/lowvideocameras to spread the information.
Readers/watchers often ask what I use: I carry a Sony Bloggie in my purse and use a Canon Rebel T2i [aff link] for my green screen videos. I also use a Kodak zi8 [which is not made anymore] for vlogging from home, and would love to upgrade to a Kodak PlayTouch.
Just remember - a great camera will not make you a great vlogger – good content and practice will.
