Everytime I hear somebody playing the JD800 I'm always had feeling to buy one but I can't find any. But if I find one it's too expensive. I like the sound of the electric piano like the one they used mostly in the Luther Vandross songs. What is the cheap alternative to JD800? I don't worry about the knobs and sliders, what I want is the sound quality and the lusciousness of the sound. I do have a JV1010. Is there a expansion card that has more of JD800's patches and waveform?
