Good spot Alan. Unfortunately, or fortunately, depending on who you talk to, I currently have my budget for any more melodicas tied up in repairs for a Professional 36.
I have the Piano 26 as listed in your post above and to be honest I was not that impressed. The hohner instructor 32B is my current surprise package. It’s Chinese made and very affordable yet it has a very pleasant sound. As they say, beauty is in the eye of the beholder 🙂
