John A Dole IV 5 This has been a great purchase. Light weight, excellent piano sound for the price. I had purchased a small casio keyboard for about 3000 JPY less which was fun, but small keys and poor piano sound left me wanting better piano sound. That one is good for kids because of all the sounds they can play around with. There are less preset musical sounds on this one, but if you are looking for big keys and piano sound, this is it.
