Stack-ON gun "safes" look to be made in the same factory (or a factory next door!) as Sentry gun "safes" in that both brands areVERY similar, so take a look at the Sentry line and compare specs/pricing before you choose one over the other. Consequently, the "same safe" (Stack-On vs. Sentry), mayhave a better warranty or pricing so compare equivalent Stack-On and Sentry models. The Stack-On "Elite" series are their better "safes" so look at one of those ifyour budget allows.
You would have to spend MANY thousands of dollars to get a true safe, but the Sentry/Stack-On gun "safes" (RSCs actually) are definitely better than the locker-room type gun "cabinets" of thinner steel (avoid those). I have several safes/RSCs, one of which is a 10-gun Sentry G2215 (older model) which is basically the very same thing as their current model 10-gun "safes" and it is better than just hiding guns in a closet or under the bed.The G2215 holds mostly ammo cans. My better security is a smaller Class B safe (a Cobalt S852C) for handguns, personal checks, home/car/bike spare keys, important papers, optics, laptops, cameras, etc. (I have a Sentry "firechest" that is in there for at least SOME fire-protection for the Class B's contents since the safe itself is only a burglary safe, nota fire safe).
So yes, I would say RSCs like Stack-On (and Sentry) are"a pretty good value for the money" as the goal is to DETER a thief, or at least slow him down getting your stuff. AND, IMO, it shows you are trying to be responsible keeping guns out of the the hands of others (looks good in court).Besides,many ofthe more expensive "safes" (RSCs) don't have much thicker steel than these entry-level RSCs so a Stack-On/Sentry is about even there. The better quality RSCs have better quality locks though (Sargent & Greenleaf, La Gard).
A combination (mechanical) lock might be preferable over an electronic lock...so consider that. All4 "safes"I haveare combination locks (including a small Sentry in my car).
And, as always with any of these RSC regardless of brand, you MUST bolt it down to the floor (and wall studs also if possible) or else it will be carried off and opened later (so if you can, put lots of heavy things in it to make it weigh more). Install it in a corner so it can't be "rocked" -- so a thief can't get body-leverage topush it over (rip it loose from it's floor mounting bolts) -- which is one reason tobolt it to the wall also.
