I should have checked this thread more often, thanks for the tips everyone. I am going to go for a ft knox or something in that class. I feel like they are are equal enough when it comes to theft protection as long as it's a big safe that can't walk away and they take some basic precautions with their dead bolts. As was said, no safe will protect valuables from a seasoned pro with ample time. It seems to me that the big difference is in fire rating, and I'm going to find the biggest one I can afford with the best fire rating. At the last gun show I went to I talked to another safe guy with fire ratings quite a bit higher than Ft knox. I can't remember the name off the top of my head, but I'm currently leaning towards them.
My biggest question now is still where to put it. Are there standard rules regarding placement? Inside wall, outside wall, etc. Inside a closet isn't possible as I don't have any big closets. I have a spare bedroom that we use as an armory, so we're either putting it there or in the garage. I personally don't like the garage because of the increased risk of corrosion and the fact that it's a lot easier to break into my garage without me knowing than to break into my house. I'm also worried about my foundation because my soil shifts a lot, but every time I bring up that concern with the various safe people they say it has never been a problem.
