To chime in, first: I'd suggest still pix, plus a written description.

generally think think that videos are much use beyond showing screen refresh type stuff. The ECTACO has an LCD screen, and we pretty much know how those look when refreshing, so unless there's something unusual about it, I wouldn't mess with a vid if it were me.
That's just my 2¢, we'll see what others think too.
