Forget about all those traffic radar detectors that have come on the market recently. The truly paranoid need far more sophisticated equipment to find out who's watching them, such as this "All in One Professional Counter-Surveillance Device."

The $350 piece of hardware can supposedly detect GPS trackers, wireless hidden cameras, audio bugs, phone taps and laser eavesdropping systems, as well as disable their transmissions. There's just one problem: As Navigadget points out, it may very well jam every other digital device in your home.
