I'm of the opinion that any safe is better than no safe. Others will argue that if you can't buy a bank vault, don't bother. What do you want to keep out? Kids? Junkies? Burglers? A dedicated, trained safe cracker who targeted your house will get in. However, I don't advertise I have guns, so I'm likely to get robbed by some punk druggie who wants a tv or stereo. He's not going to get my 800# safe out the door, or get it open.
My advice is: Get a safe twice as big as you think you need, you'll never regret it. Get it now for the peace of mind. You can scrimp on the paint job, or the features, but get one before something bad happens.
Oh, by the way, I ended up with one twice the price I started looking for, and I don't regret it at all.
Mine is a Champion and works great.
