Flash driver to Mp3 player converter?

I was just curious if any one knows where to find a mp3 player that connects to a Flash drive. I currently own a 1 gig flash drive and would like to use it as a mp3 player but am not sure how to go about finding the 'player adapter'. I found one that broadcasts the mp3s on the flash drive to radio waves for in car use only (has to plug in to the cig lighter) but i was hoping that there was one available that had a head phone jack, decently small size, and had the option to braod cast (though broadcasing is nifty its not a req). If any one knows where i can look or how to search for one on the net (keep getting combo flash drives and mp3 players) i'd love to hear about it.

Thanks
