Ofir, just to be clear, my all time favorite brand of melodicas is Hohner, and I play Hohners almost exclusively now.
The only good Hohners are the old ones and they all are out of production. Fortunately, except for a couple of high-end limited-production models, all the old Hohner models are readily purchased on Ebay.
By the way, decades ago I performed as an accordion player at the Worlds Fair in Osaka, Japan.
