i recently acquired a mount vernon vincent bach 1 1/4 mouthpiece. went to chk out the value and saw a couple out there for around $350 - $450 bucks. i tried it. seems like a pretty smooth mouthpiece. i'm currently using a bach 5 megatone and i like it better. it only cost 75 bucks. anyone know why the 1 1/4 would cost so much?
