Sold mine years ago as well for the Z7 Extreme. Killed more deer with that MQ1 than with any other weapon I own. Great bows and hope you find one for whatever reason your looking.
I have one. It is setup for bowfishing. I have the Vertix and have pondered selling it. Life is hectic and I rarely shoot. Used my xbow only this fall and doubt that changes.
Best bow Mathews ever made. Still have mine and my son has taken it elk hunting in Colorado 2x. Told him not to spend $1500-$2000 on a new bow when this one was every bit as good as any new one.
