RE: Which gun safe?
There is nothing like the secure feeling you get once you lock your stuff up in a safe. I would recommend you get a high fire rating now instead of later.
Some safes have a series of re-lockers (designed to force the locking lugs into position) in them to prevent the rookie from taking your stuff via the drill or the torch.
My safe had a faulty latching mechanism. Took a safe company employee almost 4 hours to get it open...which made me feel really secure about some common thief.
One more thing, hire someone to move it. No matter how good you are or how smart you are, the moving guys will do it better. This I know from my own dumb experience.
