I might get a safe from a big box store if I planned on putting some regular type guns in it and maybe small quantities of silver bullion and miscellaneous other valuables. It's as much for fire protection as for anything else.
Bolted to the floor and rigged with an alarm, it would do an excellent job of protecting valuables in most cases. Hiding the safe is also a good idea. Out of sight is out of mind, and if they can't find it in the first place, then they can't crack it open.
If you're really accumulating lots of things that need serious protection, then by all means, invest as needed. Build an addition onto your house for a used bank vault, then rent out the space for safe deposit.
Here's a big Mosler vault from the 1940s for $15k. It might be old, but it's still strong.
Silent Running, by Mike and the Mechanics
About 2 weeks ago, I bought a Cannon safe from Costco. Did a bit of research and I couldn't beat the features for the price (under $900.00 out the door). It is a key pad with no key backup (one that let me set my own 6 digit entry code). They also seem to have a pretty comprehensive warranty. If anything goes wrong with it, someone tries to crack it, gets caught in a fire or flood, they will repair or replace it free of charge. They even pay for a locksmith if the locking mechanism malfunctions and shipping, if that is required. Hope I don't have to use any of that. Also has very configurable shelving and L.E.D interior illumination.
I need to get my safe bolted to the floor. My safe was a cheap ****'s special a while back. It was just to house my firearms. I need something more secure though.

Yeah, I got a Cheap double hand gun safe from GALLS.Com and man no padding at all. I got another cheaper one from Dirt and this thing was way better then the Galls one by a long shot. 1'' foam all the way around top/bottom/sides/even on the door it's self. I took all the foam out of it and put it in the other safe as it's bigger and has a pull out shelf for gear. I drilled holes in it and bolted the other one on the top of it took the left over foam and put it in the Dirt safe. The bigger bottom one if for my gun and gear and the top one with some foam is for my ammo. It works for now seeing as how i do not have the money to drop on a 500 or up safe.
