Good thing to keep kids out of the guns and honest people out like you said. Sure won't keep a criminal out longer than a few seconds. I don't have a super expensive safe at the house but I picked up a Sentry for $150 off of craigslist a few years ago. It is a 14 gun safe, and I'll either buy another one or upgrade to like a 48+ gun safe later on.
I have a 10 gun stack on and a 12 gun oak gun case full as well out at the farm. I'd sure like to get all of my rifles in one location. However I've pretty much always got something to shoot close by.
