Greywolf, get the biggest safe that you can afford. A few more things may have to go inside sometime.

+1 (at least) on that. We camp regularly for five days at a time in the summer and my wife's jewelry goes in there and, always, important papers such as the deed to our house, marriage certificate, wills, and financial papers reside in there without crowding the important stuff like guns.
I bought an American Security large safe some 10 years ago and paid $1500.00 plus another $200 for delivery. It sits on concrete in a fairly small storage room on our lower level and would require removing several doors to steal it even if the thieves could work up the muscle to do so. It has some thirty or so rifles and at least that many handguns for added weight that wasn't there on delivery.
They don't wear out and, amortizing the cost over a lifetime, it's cheap insurance.
You'll be surprised the number of things you will want to put in there when you get the safe. GO BIG.
