Pro Music Tools in Germany has a few. Prices are on the high side. No affiliation, never bought something there.

Sterling basses aren't as popular because every bassplayer automatically thinks Stingray when you mention Music Man. At least they still make the Sterling model, they must sell enough of them to keep it in production. But the Stingray outsells it by a huge margin. The Sabre Classic had a short-lived reintroduction but that one is gone (again) due to lack of sales. The Sterling, Sabre and Stingray are all fantastic basses. I always wanted "that MusicMan sound", I had never even touched let alone played a MusicMan bass. I bought the sleeker Sterling 4H online. It's everything I hoped for, a fantastic bass.
