Late to the party, but I’ve got the alto Ecodear, regular plastic yamaha, an Aulos and the Zenon 415. I play the Zenon the most because of the pitch, but the Ecodear has the warmest, richest sound of them all and clearly stands out. Unless you ramp up to a Bernolin, which has a wood block and sounds like an ebony recorder, the Ecodear is flat out the best. I wish they made a 415 in that model.
