Are suicide bombers cost effective?

Insurgents bought suicide bomber - Afghan spy agency | Reuters: "'The detained man added that a commander under Hakimullah Mehsud sells suicide bombers at 6,000,000 to 8,000,000 Pakistani rupees ($70,000 to $93,000), to the Haqqani network for suicide missions,' the statement said."

A Tamahawk missle costed $US 569,000 (1999).
