I have a Ketron SD4. I am selling my SonicCell. The SonicCell is killer for funk/fusion etc. but the Ketron natural acoustic sounds cannot be touched. THey are both great units. I would have been thrilled with the Sonic Cell had I not owned the Ketron to compare it. It really depends on what kind of sounds you want. I am a straight-ahead jazz guy, and love the natural sounds of the Ketron. If I were more a rock/funk player, I would gravitate toward the Rolands.
