a1abdj appears to be an expert in the subject. I am not. I am however, a reasonably intelligent guy (at least I like to think so). I have spent many hours researching this for my own project. I have seen in person the Smith, Ft. Knox, AMSEC, Graffunder, Browning, Pentagon, Prosteel and Sturdy doors. IMHO, the Graffunder was the nicest. That said, I am a value shopper and for well over half the cost, the Smith seemed like a great value to me. I would have forked up the dough for the Graffunder if I thought it was necessary.
I really looked over the Smith door during the installation. I just can't see how anyone outside the guys from the Italian Job are getting through that without some serious equipment and hours of work.
Is it the best? No. But it seems like the best value to me. I'd rather take the $5,000 - $10,000 difference and use it elsewhere.
