I have an AMSEC CFX452020 Amvaultx6 American Security TL30X6 High Security Safe for sale.
Currently, this safe is going for $10,00+. I'm selling for $6000. I've only had it for 4 years and it's in great condition. It's heavy, like 2300 lbs, but is sitting on a pallet so it can be moved (CAREFULLY!) with a floor jack.
