I have the opportunity to acquire a safeguard SD107 safe for free, I must only pay to move it. I'm trying to figure out if it's money well spent on a decent safe or not. I have the combination and there is also a keyhole for which I have the key. I'm not sure what the purpose of the key is. Internet searching provides lots of garbage from eastern Europe and Nigeria. I'm hoping someone knows if its a quality safe or not.
