The advice about getting as big as you can is true. I have found out (the hard way) that with safes, you get what you pay for. If the price seems too good then you are probably getting a piece of crap. The caveat here is that even crap can sometimes pull through for you...
I just bought my 3rd safe, and yes, I do use them all. I bought a Centurion because the price was good, and it was highly fire-rated. The icing on the cake was a nice S&G lock. I refuse to get the digital locks, because I have never seen one that works well. Anyhow, I ordered the safe and when it was delivered, and we were shoving it into position, I noticed a big fat MADE IN CHINA sticker on the back. Man, I tell you, I turned about three shades of green, and did a lot of cussing. When I got over it, I came to terms with the fact that its a decent safe for short money.
