I've been playing casually since the mid 60's, I play simple folk melodies and re-tune the first two draw notes of my Richter tuned diatonics to get a more complete major scale on the lower notes.
I like the top of the line Herings, though I have not found them around lately. Right now I have a Hohner Big River in my shirt pocket, not bad for the price, I have played many in my lifetime and my favorites are Hering from Brazil, Hohner from Germany and Lee Oscar made by Tombo in Japan.
I agree with the comment on the Hohner Special 20 though I have seen three different models named Special 20, the first one came out before the MS series, very similar to the Marine Band 1896 but with plastic comb and screwed on plates, then there was a cheaper one made in China and then the MS series model, the first German model was my regular for a long while.
I've looked around with no luck for the new Hohner Marine Band De Luxe, I like to see before buying so I will keep looking, it should come to Mexico City some day...
