I got a relatively low-end Sony CDX-MP40.
Fit perfectly.
Plays MP3s. Better than a CD changer.
You can get about 10-12 CDs worth of content on one CD in MP3 format. Less clutter and hardware expense.
Around $160 net from pcrush.com
Totally happy with it.
Search for my thread in Car Audio that describes how I gutted the connectors from the back of the old Becker to facilitate wiring.
