It may just be me, but it seems a lot of people forget traditional instruments when music is discussed these days. The pervasive image of a four person band with electric guitars has replaced that of the orchestra and big band, which featured far more instruments. Instruments like saxophones, trombones, and flutes are still played of course, and variations of all grades can be found at http://www.wwbw.com/Saxophones.wwbw for competitive prices - from those used by students to those used in concerts.
