I am looking for an economic alto sax upgrade (went all through college using my Bundy II and school's basic Yamaha). I really don't have a use for a high end alto since I'm a bari player first and foremost. I recently found a Buescher True Tone online for $395. Would that be a worthwhile investment? Its serial number indicates a 1920s model. I really like vintage horns, so would it be better to keep looking?
