I'm trying to create an interrotron setup so I am buying two teleprompters. I'd like a fairly large one in front of my main camera, a Panasonic HMC-150, so the subject has a larger face to look at.

Does anyone have any feedback on the quality of the following teleprompters?

1 - http://www.lcd4video.com/products/Professional-Teleprompter-Kit-w%7B47%7D-1...

2 - Hardware | Electronic Script Prompting (http://www.prompting.com/hardware)

3 - Model 1550 Prompter Head (http://www.lowcostteleprompters.com/hardware/m1550.htm)

the first is an LCD 4, the second is electronic script prompting, and the 3rd is Stewart instruments.
