External speakers/ docking station

I am interested in MP3 player, Mac 10.4 compatible which can use external speakers and / or a docking station

The Clip and Clip+ have all of that, I believe (I’m not a Mac guy, and so am not certain about Mac 10.4 specifically).  Macs can cause issues when transferring files to the Clips, though; use of KopyMac (free software, available via the Internet) to transfer files avoids that. 

For speakers:  just connect them to the Clip players’ headphone jack.  There is no Clip docking station.
