From the Boeing web site:

The Joint Direct Attack Munition — or JDAM — is a low-cost guidance kit that converts existing unguided free-fall bombs into accurately guided "smart" weapons. The JDAM kit consists of a new tail section that contains an Inertial Navigation System/Global Positioning System.

In actual use these weapons have proved to be very accurate and highly reliable. They can be accurately delivered in virtually any weather conditions. JDAM can be launched miles from the target and safely rely on the navigation system to update the weapon all the way to impact.

Speaking of JDAMs I saw an intersting quote yesterday.

"GPS puts the 'dam' in JDAM"

Thank-you National Security Space!

I want one, where can I get one? Ebay?

Low cost? I understand that each kit sells for over $20K(US).
