There is a big difference between Selmer USA and Selmer of France. Selmer of France manufactures a wide variety of instruments including clarinets and saxophones. Among saxophonists, the saxes made by Selmer of France are for the most part considered to be the very finest, especially their Mark VI series which they no longer manufacture. They also revolutionized the entire sax world before the Mark VI when they introduced their Balanced Action model - this was the first saxophone with the finger / key mechanism that is now standard on all saxes being produced today.
