Jacko,
My RAM mount came as a couple of different pieces, the IPad cradle (RAM-HOL-AP8U),
and the base and swiveling arm, (I think mine is RAM-101U-D).
I find this setup is good, although not cheap once you get the couple of different components. The mount has to be screwed/bolted to a console or something solid, which you mightn't want to do, or they do have some other options such as suction cups. They are a component system so the iPad cradle will work on any of their mounting arms. I think they might have ones that attach to seat rails too?
