Hello Lowboy, I have considered the Cassotto many times but yet to pull the trigger, it seams you found a fantastic deal on them. Like Troy I am very interested in hearing your comparison. I don’t know if you saw my discussion on “Old ver new” about the Hohner Solist I purchsed Like the Professional 36 the Solist is a single reed Melodica. if you click the picture you can see the inners. A very nice instrument.
