I've been using an Apogee One Ipad/Mac for recording both bass, organ and guitar into GarageBand recently. My band has recorded 5 songs at a real studio but on a few tunes I'd decide to rework a bassline or add a bass VI track or even a guitar or organ track after the session was over. The studio has been awesome about substituting or adding new tracks to the project and the Apogee has done a great job providing a conduit for clear solid recordings. I feel like this has saved me a lot of money in studio time without sacrificing quality. I would not use it for voice or drums but for anything recorded direct - its been great!
