Last year I got a Medeli SP-4200. I actually discovered it when I was reviewing the new Kurzweil products. I discovered that Medeli was making the portable keyboards for Kurzweil. The comparable Kurzweil model is the KA-120. I purchased the Medeli SP-4200 from Sam Ash (dealer for Medeli keyboards) for a much much lower price than the identical Kurzweil KA-120 that Sam Ash was listing concurrently. Exactly the same two instruments.
