I'll tell you from experience, a good safe is only made as well as it's maker makes it..... Having worked in construction many years, and having a reputation for getting the job done, I've been called several times to open safes after a local man passes away, leaving it's contents a mystery to family members. I've had some real surprises, too. (like the older gentleman that had an extensive pornography collection locked up)

Usually, the family has a good idea of what's in it, so there's not too much of a surprise. There's something to be said for a safe that costs more than $2000. Not that a Liberty and such are useless. The average thief smashes and grabs. They're too cowardly to stand around and take their time to open even a good locker. Not to mention the physical exertion is too much. They're usually lazy, hence the reason they're stealing. So a Liberty safe is a good investment, IMO. But it doesn't take me long to open one. And a Browning? ProSteel Security Systems, out of Utah. Bottom of the line models sold in the past are easily accessed, more so than Liberty's, but upper line models are pretty tough, requiring more effort or tools. Plasma torches make short work of steel plate, but they're not too healthy on the resale value.... :-laf
And someone made the comment about sentimental value of a firearm.... "One or two are worth more than a good safe." I think there's a lot to that, too. Personally, I've had several brands of safes, even built some of my own and some for other people, and I think one should spend a proportional amount of money in relation to what you own. So it costs you the price of 4 rifles to buy one.... what's it worth to keep the other 5-6 you own safe?
But if you're at the hardware store, bragging about your $12,000 Barrett M82, showing pictures of your living room, garage, and front yard, I think you're less than intelligent to take it home and put it in a Harbor Freight steel lock box in the sunroom on the back porch next to the doggie door in the screen door where the windows won't lock..... with a towel over it....
In another spectrum, I understand the desire to just keep them secured. A good steel locker is all that's needed to keep them from prying eyes and pre-teen (uneducated and coached) children.... A federal requirement, I might add.
Personally, my favorite is a concreted closet with a solid steel safe door, or lockable heavy door. It doubles as a safe room from home invasion and, living in "Tornado Valley", as an acceptable storm shelter. Cheap? No. But if my wife and kids are in it, I can't find anything I value more and have more desire to keep safe.....
