Yamaha portable keyboard, PSR270: http://usa.yamaha.com/products/musical-instruments/keyboards/digitalk...
Complete with adapter plug, stand for keyboard and stand for musical scores. No instructions.
It's old and scruffy but still works fine, can be plugged in or takes batteries. Lots of settings, including different voices and styles, on-screen information of what chords are being played, and the ability to record what you play. May suit a musician or a family (I had lots of fun with it as a kid).
May be too heavy to carry, please pick up with a car.
