Sony DVPCX995V 400-Disc DVD Mega Changer/Player (2009 Model)
awesome
Throw out your disc racks.  this will hold most music AND dvd libraries.  easy to navigate the menus.  the only drawback that I can find is that when you power up this unit, it automatically starts the last disc you played.  This blocks access to menus until the disc loads completely, then you have to hit STOP. Then you are free to navigate
