New Fuji Camera

Hi folk's sorry if there is a similar question to this elsewhere.

I'm looking to buy a new camera in the fuji range and have been looking at S2800, S2950, S2970 and S1730.

I know all these camera's are fairly similar but which is best? I'm going to be using it for sport so high speed continuous shooting is important as is zoom.

I know there are better camera's but they are out of my price range as i'm just a beginner.

Thank's
