To add to the mix - sigma makes another pair of lenses that, while a bit more expensive, might also be worth looking in to:

• 40-800mm - slower focusing, but supposed to be good quality, matching, if not exceeding the tokina 40-800mm AND it has sigma's version of image stabalization!
  
• 50-500mm f/4-6.3 - faster, quiet focusing lens. Also supposed to be a really sharp lens.
  

Though now i'm reading that sigma's image stabalization doesn't work with canon camera bodies.

The teleconverters cut your aperture. More importantly - I would imagine (excepting the highest end lenses/teleconverters) i could see it affecting focus speed/ability.

I like primes in theory - but in practice, in the situations that i've been wanting a longer lens, i've also been having things shift enough that if I were shooting primes i'd be spending half my time switching lenses : )
