35 years of tool and die making has let me replaces 1000's of threads that people have stripped. As Beezer says...Helicoil is the King.
But watch the video Laurel perry posted. There is a whole tool kit you need to install a Timesert $$$
#1. Helicoil - strong threads and minimal toolkit
2. Keensert(self locking) - installs with a standard tap set. see link http://www.newmantools.com/kee.htm
3. Timset - Good but lotsa tools req'd
