Get the BIGGEST,best fireproof rating,best built safe you can possibly afford. The fireproof rating is no brainer,but the size requires explaination. Basically,the better built safes will be heavier due to the thicker steel they're made of,and the bigger they are,the harder it'll be for someone (or group of someones) to pack the safe off-whole kit & caboodle. The largestAND best builtsafes provide the most security of all. Another thing I've found is you can ALWAYS put more in it,but you CAN'T make it bigger-just like a garage-and believe me,sooner or later you'll want a bigger safe. A couple more things that need to be touched on is getting a goldenrod dehumidifier to put inside the safe,and BY ALL MEANS-lag bolt the safe you choose secrurely to floor!!!!! I even went as far as cutting a steel plate to fit in the bottom of my safe and using several 5/8" grade 8 allthread lag bolted completely thru the concrete and using lock washers/nuts.
