IMO for what its worth. And since i deal with these on a regular basis. As im a certified locksmith whom delivers and sets up gun safes for various companies in our area. As well as im also a certified technician for numerous safe companies. So when something fails i'm the one they send out in my area to fix the problem.
Never buy what u "think" u may need. Always buy something a little bigger or perhaps the one that u think is a little too big, lol. I know this sounds stupid but its true. I know MANY people who bought what they thought was just the right size. 6 months later they realize they dont have any room left in their safe. Space fills up fast when u realize u know how something thats big enough to fit most of ur valuables in......Too much room is always better than "oh no, i dont have any room anymore".
Keep in mind, the prices of gun safes are steadily going up year after year. The material to build them is going up, so the manufacture ends up going up on their prices. So next year the safe u buy tomorrow will probably cost a few hundred more if not another 500 more.
Buy something with some weight to it. Take ur fist and knock on the "side" of the safe, see what it sounds like. Does it sound solid? Or does it sound like ur knocking on a beer can? Dont buy the one that sounds like a beer can. The door is always the most secure part of the safe (so dont knock on the door). If u knock on the side and it sounds solid, i can promise u the door is way more solid.
Fire proof, do u need it? Or do u need just burglar? Yes there is a difference between them and there is also a price difference. A BF (burglar fire) rated safe cost a considerable amount more than just a Fire rated safe.
American Security (AMSEC), Browning, Liberty would be my top 3 picks and in that order.
For what its worth, if u are a first time buyer and dont want to spend a ton on a descent safe. I'd look into a Liberty and u will get a good bang for ur buck. They make a great safe at a very reasonable price. And i very rarely have a customer that has a problem with theirs. Ur average criminal will "may" get lucky enough to beat the lock off the front of the safe. But lets face it, he just made his job 10x's harder than it was to start with.
