I looked at that one, but it is infact a firesafe made of plastic, with a really nice lock on it. If I were a thief, I would just cut into the plastic material that it's made of rather than fuck with the door.

this is the one I was going to get However, it's actually cheaper on newegg.com

This one has a circular lock, which I would consider the primary mechanism, and the electronic keypad as just a convienence to save myself from digging up the key. It's not as lavish as some of the other safes, but for the price it seemed to be the best quality. They have a smaller model available by the same company, but the inside lock looks significantly smaller than the larger unit. I believe it can be bolted to a wall too, which is extremely preferred.
