i was going to post a link to them. their document safe within the main safe is a very nice touch. i agree that they're about as good as you can get until you step up to a commercial safe. most home safes are actually classified as "residential security containers."
one other reason to bolt down...a loose safe can easily be overturned by putting a prybar between the safe and the wall near the top. the bottoms are usually 12 gauge, which can be cut open with an axe without too much difficulty.
oh, and i hate thieves. the treatment of thieves is one thing out middle eastern neighbors get right.
