I'm looking into getting a camera crane or a jib but I'm really wondering what's the main difference between the two?

Thanks phil, So the jib can be used for crane shots and the typical jib movements where you are controlling pan tilt from the front, But the crane can only do crane style shots but is cheaper?

I can't really afford the Kessler, it's just too expensive to import but I have been looking at Hague/Cameragrip cranes and jibs and I'm impressed with what they offer at those prices, you have any thoughts on these Phil?
