One of the Liberty safes from Gander Mtn with an electronical, push-button combination lock (smaller model than previous page). I would prefer a non-electronical lock, but it isn't locked when i am home.
My cats find it very interesting. I think it is probably overkill considering my taste in firearms. I also think if someone offered me half what the thing cost AND came to pick it up, i would take it and be happy with one of the Stack-On cabinets.
If you have the option to get the door panel attachment with holster-type storage for some handguns, get it.
