http://www.ravelco.com/ friend of mine in midland had this, saved his 2005 dodge 2500 from being stolen, had to replace his door lock and his steering column. after it had been broken into.
lojack can be deactivated (more difficult than onstar though) but if the theif has messed with lojack before he/she probably knows how to eliminate that device. its not really an anti-theft, more of a vehicle recovery item.
