Let me also point out that the QMA has a mating cycles rating of ~100, whereas the BNC is minimum of 500. If you plan on connecting and disconnecting the APX on a daily basis, the BNC will be more durable in the long run, cheaper to replace annually, and easier to find.
Get one each of these, and call it a day.
