The safe isn't going in a garage and will need either specialized machine or strong man crew to get it inside where its going, so curbside delivery is a no go. I simply need more local support.
As for Sturdy's check out their videos. They're pretty awesome.
One thing to note is that their comparison video of an axe attack against an AMSEC BF is done against a BF without the interior 4ga liner, but rather the standard liner. Sort of misleading, given you could have it for the same price point as the Sturdy and basically have the same protection against an axe attack. AFAIK the concrete fill is more troublesome for someone trying to cut the safe open, not punch it open with an awl/axe. Something about dissimilar materials and the type of blade you'd be using to cut open the metal.....IDK, maybe someone in here with more know how can comment on that bit.
And, for the price of a maxed out Sturdy, you might as well just buy yourself an actual TL rated AMSEC because you're already there price wise.
Nothing. Everything you laid out is why I've still got my Stack-On cabinet. Only now in my new home with a dedicated arms room, concrete floor and fire wall x2 border am I getting a more substantial safe. Even then, due to its location (deep in the alarmed house behind a hardened steel frame/door with high security locks, in its own room, itself being inside a house with security glass and steel frame/doors with high security locks), staying with a cabinet is probably not an irresponsible decision. I just want it.
That head ain't just a hat rack, buddy. You one of them thinkin' men.
If you mount the security cabinet sturdily to the wall and wooden floor, and with the safe in a corner facing a wall, it makes it harder to pry the door as well. They could always spend the time to pry it off the wall (since it's basically wood screws, not bolts in concrete) but that's also unlikely for your living situation with neighbors. If you're worried about someone purposely targeting your safe then yes, you need to jump up quite a bit in price/capability. The one reason you might want a safe in the $1500 range, however, is to give you protection against an unskilled crew with a sledge and prybar. So, it does get you something, but again that can be mitigated with where you put the cabinet and how it's positioned relative to other structures.
