Sony CMT-EH15 Micro HI-FI Stereo Music System with CD /AM-FM Tuner / Cassette / MP3 CD Playback & Remote Control.
Extremely lightweight.  One of the few products I found that plays cassettes, as well as CD, radio, etc.  This is perfect in the small office space where it's used in our home.  Somewhat difficult to make settings, requires looking at the manual.  A good product for the price.
