When I asked friend that is a locksmith what is a good safe to buy, he asked how much money can you spend and what is the purpose. The more you spend the better safe you get and mentioned that Cabellas had some good safes. He also told me any safe can be broken into.
Here is an interesting thread on safes:

Personally, I am limited for space, I didn't have $1000 plus for a Cabellas safe so I picked up a 14 rifle SentrySafe. As safes go it is low end, but it keeps my little ones from the guns which was why I wanted it.
If someone wants to steal it, they are going to have to get it loose from 1/2 x 5" Wedg-it concrete anchors and 1/2 lag screws in the wall....while they are dealing with the dog and snoopy neighbors on all sides. If they drill it, I am screwed.
My buddy Jerry makes finely crafted access doors and access panels that look like part of a wall....add that with a good safe and your guns would probably be as secure as you could get them without a Armed Guard.
Good luck!
