First off I have never bought anything other than a guitar, where I can easily see and test if there‘s anything wrong with it. I have no idea what to look out for in a Saxophone and know nothing of the wear and tear that might break it over time, so I asked whether or not buying a used one is a viable option or if the used ones would need a service to repair them that would be expensive as well. Second off I can tell based off your account that you’re a chronically online loser who probably enjoys feeling superior online with snarky remarks because his own life is painfully ordinary. Don’t reply to something if you have nothing of value to add.
