I have either APK or XPK, I can't remember which it is as I bought it 8 years ago (bad memory).
It's been a great kit, the one I have is the fusion model, natural finish. The hardware is reasonably heavy duty. Can't think of much bad to say about it. One of the clamps that tightens down the ball/socket on the high tom snapped off when I was tightening it, but that was recently and just part of normal wear and tear.
