Clip Sport or Sanza Clip +

^+1.  And, as responded to you earlier in a separate thread, in response to your inquiry there:  http://forums.sandisk.com/t5/SanDisk-Clip-Sport/SanDisk-Clip-Sport-Firmware-1-17-released/m-p/333549/highlight/false#M1219.

Do note:  the Clip+ does not play aac files–if you want that capability, go with the Clip Zip, which can play them (although not always, unfortunately, depending on how they originally were encoded).
