The model of the instrument we bought today is kind of like this yamaha s90xs. It is a Yamaha brand too but color white. It was the top of the line which cost us an arm and a leg but hubby said that when it comes to our children's happiness, he would rather spend an extra amount so they get the best. I don't always agree with him but I agreed on this one since it was really nice. I hope that the kids would love it as much as hubby and I do.
