Going out on a limb here, but..................... I bought a safe at Sam's Club a few years ago. I've been very happy with it. 1/4" steel plate for body and door, 1" chrome steel locking door pins, external hinges, @700lbs empty, and it cost around $700. Is it "the best"? Nope. Is it the most expensive? Nope. Will it do the job for the vast majority of "security detail" that I need? Yep. It's UL fire rated, but I don't recall the exact rating at this moment.
It is UGLY green, but hey, "I" wasn't buying a piece of designer furniture, some folks do. Sam's Club still sells it, it just says Winchester now, and NO, it is NOT made by Winchester. The manufacturer just paid a price to put the name on the door. Take a look at it and see what you think, it definately fits your budget for under $1000. It is around 60"t x 26"d x 30"w.
700lbs empty, and a thousand-ish "fully loaded", noone is going to toss it in the bed of a pickup. They might drag it out of my home with one, but that "might" get some unwanted attention. Get the picture? Given enough time and resources, NO safe is 100%, guaranteed, break-in proof.
External hinges do NOT make a safe easier to break into, provided it has internal locking pins. Once the hinges are cut, torched, whatever, the pins still hold the door in place, provided the pins are on ALL 4 sides of the door. Anyone that has that much time, will eventually get into it one way or the other, and most likely destroy the contents in the process. "Home" safes are designed to stop smash and grab, as well as motivated home burglars. They will NOT stop professional thieves, the FBI, CIA, or any other Government black ops group that are stealing your secret stash :banghead:
