Seeking opinions and advice about low cost braille displays

Hello, all!
I'm finally in the market to purchase a braille display for use with my iPhone, and I was hoping to get some thoughts and opinions on the Braille Me, as well as the Orbit Reader. I'm a little more interested in the Braille Me because of the cursor routing buttons, and I can't seem to find any reviews on it online. I'm also interested in hearing about using the Orbit Reader with the iPhone. What you like about it, dislike.
