we bought a piano from a music store in rob.magnolia. casio brand, it lights up to tell you which key to hit, and connects to the ipad, and weighted 88keys, and i dont know what the feature is called but when you press hard it plays hard when you press soft, it plays soft. for 12k. my 8yr old seems to like it, then again what does he know. the piano teacher just asks that the lighted keys be turned off. my wife is sneaking in some self learning piano lesson time herself. i also tried it, apparently, i dont have command of my individual fingers.!
