Looking for a SanDisk w/ rapid fast forward and rewind

I am looking for an mp3 player with rapid ff and rw which is nice for audio books.  I just purchased  sansa clip does it have this function.  If not is there one that does?



You can advance your way through a particular tune if you press and hold the “Skip” buttons, forward or backward. As I discovered, you have to press then hold for at least a couple of seconds before the advancing starts.

The Clip does have progressive seekings: http://forums.sandisk.com/sansa/board/message?board.id=clip&thread.id=14902
