I am also looking for a safe so I can't help you there. I do think you will get more answers in a different forum. Maybe the finance one?

I would say that, like anything else, you get what you pay for. The lower grade safe would withstand a smaller fire than the more expensive one.

Beyond that you'd have to find someone experienced in how they actually survive fires, which may be hard to do.

I would go with whatever you can afford, and remember that anything is better than no protection at all. :-]

1. Have you looked at the reviews on Amazon? Sometimes those provide helpful insights.

2. Do what I do: Put irreplaceable items in a safety deposit box at a bank.
