Our doubling flute is a student Armstrong, which was purchased at a Goodwill store - with a complete overhaul, we have less than $200 in it. It works just fine as a non-first-line instrument. Yet I know that when I worked at band drives where we tried to get students to rent instruments, we stressed the dependability and consistency of Yamahas. Sometimes we would stress a certain brand that had a gold plated head joint (as if that made any difference to a beginner?) Any opinions for those who do not play flute as their first instrument but would like to get a decent, resalable instrument?
