Have you tried posting on The High Road. There is a guy there, name has slipped my mind, that seems to really now what he is talking about. Zylkan safes or something like that. Do a search over there.
Don't tell anybody over there, but I hang out here sometimes too
by the time they arrive...be too late even with the fire ratings i see..compounded buy a wood floor
If the fire rating isn't important, that gives you the option of getting thicker steel for the same weight. From a security standpoint, that's a very good thing.
In the price range of 1500-3000 I would look at the Amsec BF series
For the money, I think the AMSEC BF series is the best buy in it's price range. These safes use much heavier doors, and composite injected bodies. These (and the Graffunders) are going to be about the closest thing to a real fire rated safe in a gun safe package.
AMSEC is also a real safe company. They are one of the largest safe manufactures in the US producing upwards of 60,000 safes a year.
Above 4k I would look at the TL30 Amsec or the Graffunder.
This price range opens you up to a variety of real safe options. Graffunder builds an excellent product, and their line consists of heavy steel plate with an injected barrier. The AMSEC (and others) offers a variety of composite safes that offer high security, but lower weights.
What should we be looking for fire rating, water proof, lock. What are other important ratings?
Any ratings on safes that mean anything in the US are awarded by UL. I'm not aware of any gun safe on the market that has a UL fire rating, and very few that have a UL burglary rating. Most safes are not waterproof. The locks are also rated by UL, so you'll want to make sure the safe has a UL rated lock as well.
What are the best companies
This really depends on a number of factors.
were are the best place to buy them?
From me of course
If you're rather buy locally, I'm sure I could point you towards somebody in your area. You're better off sticking with safe companies as opposed to sporting goods stores. They will be better able to show you the differences and provide you with accurate information.
