Some have had success with the Kenko PRO DGX 1.4 TC.  I use it with a 7D, and find it works best with the outer focus points (contrary to my expectation that center point would work best).  IQ is good (but probably not as good as the naked lens and cropping the image).  Some hunting, especially with the inner focus points, but the hunting isn't bad if you pre-focus the lens close to the subject.
