Packed with great features such as Casio's famous Lighted Key Step-up Lesson System, audio inputs for a MP3 player, Mic Input, USB port for MIDI implementation. All this makes the LK-270 more fun and easier to learn to play music. Only 4 months old and cost is over $200 new! I am also including the power supply (usually sold separately). I am selling this because I would like to move up to a larger piano now that I am getting better. Location: Kihei it's NOT ok to contact this poster with services or other commercial interests hawaii
