I've never purchased anything from A4L. But in all of the online discussions I've ever run across, they are the most recommended place to get great deals on refurb'd Onkyo gear. I don't recall ever reading of a bad experience with them. At least, nothing systemic.

If A4L had something I wanted, I wouldn't hesitate to order from them.
