DogDoc,
I have 3 Libertys and I can't tell you how much peace of mind they gave me. As noted before, buy the highest fire rating you can find.
Also, another consideration, is the safes like the Browning, with the outside hinges, All one has to do is pick the door off the hinges and then one can move it in two pieces. Even if a thief chisels off the hinges, he still cannot open the safe. They have dead bolts all around the circumfrance of the door. This would be a consideration on a safe that weighs in excess of 600 lbs.
My buddy has two Heritage safes. ONe weighs 620 lbs, and the other about 800. The lighter one came up out of his basement easily with about 4 guys. But the other one was a royal PITA.
The other reason I would prefer exterior hinges, is that I have bumped numerous of my stocks on the interior hinges.
Hope you're not like me... I always have to do the wrong thing 2 or 3 times before I learn the right thing...
A 1000 lb safe witht he door removed will move about as easily and 600 lb safe. I would assume my Libertys can have the door removed... I'ver never tried it. But I'll know when I move...
