Paranoia Express

In case a safe room doesn't give you enough peace of mind, you can also equip your bedroom with the Quantum Sleeper (patent pending). This monster cocoon allows you to encase yourself, and a like-minded paranoiac who is willing to share your bed, in the finest available polycarbonate. The list of features shouldn't be missed...

If you have more dollars than sense, you may also want to put these hide-a-doors on your wishlist. These make me laugh; every installed door that is pictured on their website is 200x more obvious than any secret door in any first-person shooter. Even the secret doors in the original Wolfenstein 3-D (e.g. push the Hitler portrait to get the machine gun) were harder to spot than these are.

Of course, if you're really this paranoid, maybe you should just stay home and watch the movie "Panic Room" -- don't worry, you don't have to leave the house to get it... You could always add a DVD player to the list of essentials for your bomb shelter.
