Casio WK-245 Piano 76-Key Portable Workstation Keyboard. I'm a drummer and had this in my practice room. It was used all the time. Always sounded good and as far as I know everything works.
Same keyboard on Ebay is priced from $80 and up plus shipping. It comes with 6 new D batteries ($15). There is no power cord.
$75 Cash. Can possibly meet somewhere to complete transaction. Text with any questions.
