I had a pistol box with an electronic lock. Eventually the lock failed and I couldn't get it open without the key. I still use it but just use the key. As far as big safes anything you get between 1-2k is probably going to be about the same as far as security. Anything to keep a real-live safe cracker out is going to cost over 10k, I'm sure. I have a Cannon safe that holds all of my 70 or so pistols that has USB hookups in case you want to store your home network computer in there. I thought about putting my security camera DVR in there but chose to hide it in the rafters of the basement instead. Safe is 6' tall by about 3' deep and at least 4' wide. I got it on clearance at Tractor Supply for $800.00. Same safe was 1300.00 at Dunhams.
