Probably not going to get your attention enough to chase this company's products down, given your location in Arizona & thiers just north of Waco TX on 1-35...but the best safe features I've found in my search is from a small custom mfg'er called Security Products in Elm Mott Texas.
Look at the unique key lock system that is a signature of their safes, along with a laundry list of whatever else you want in the way of hinges, amount of American Made steel, fire ratings & length of time yadda yadda in everything from Vault Doors to lil bitty household safes. Ain't Cheap, but quality never is.
I'll own one of these as soon as I can stop spending reno $'s on this old house we bought in east Texas.
