My friend and I thought it would be cool to try and purchase a sousa for pep band next year (because our school uses contras), and paint the bell of said sousaphone in school colors or get a cover, does anyone have, or know where to buy a super cheap beater sousa like that, we could buy a neck and bits if it doesn't have them, however i'd like it to be playable or almost playable, and cosmetic condition is irrelevant as long as the dents don't mess with the playing too much. Also, because we would like to paint it fiberglass is preferred even if it's just the bell that's fiberglass.
