I would take this (76 model) over any of the MOTL arrangers. I would take the PA4x and/or the Genos IF they were the same price (that's never going to happen). This is because 1) this unit offers more sonic possibilities; and 2) I have no strong desire for an arranger KB at this time. Plus, this thing has a lot of bang-for-the-buck; I'm seriously considering ordering (pre-ordering actually) one. I'm just afraid I'll still want a dedicated TOTL digital piano.
