That's fair.
This decision is one of the few that is a bit overwhelming, and something I've been mulling over for years.
I've been holding off on a safe purchase for a while because unless you spend big money, you really aren't getting a "safe", and you have a multi-thousand dollar heavy item that can maybe hold someone who knows what they are doing back about ~5-10 minutes.
On the other hand, I doubt many robbers are showing up to heists with plasma cutters, and most jobs are "smash and grabs". It would prevent that tweaker that's looking for any easy pawn shop sale score so that he/she could pay for their next hit, at least they wouldn't be doing it with my TacOps rifle. I'm not sure how many of them carry tools and the knowledge to allow them to break into a Liberty "safe", I really don't know.
It's literally a big purchase - it's a large, heavy, space consuming object, and a few thousand dollars is a lot of money when I currently don't work. It would certainly piss me off if a robber peeled it open like a tuna can in a short time, and makes me ponder what I need.
