Check and make sure the safe doesn't have drain holes in the bottom like one I saw before. A friend of mine had his stolen out of his house, the thief must have known what type of safe he had. The thief flipped the safe on its side, used a cordless Sawz-all and used a carbide metal cutting blade. They simply cut open a giant hole in the bottom of the safe and grabbed all sorts of goodies from inside it.
Nice safe with a gigantic fatal flaw. If you are home 99% of the time, no worries with it being 200 lb.s, but if you leave for 24 or more hours at a time, any thief could just tip the safe, and just cut it open.
