Thanks! I have a 2x II extender, which I use with my 70-200L f/2.8 with a marginal success. Yes, you do definitely lose some degree of quality. The question is whether it's at acceptable level to YOU or not. Since you're thinking about using it on your 200 prime, you probably won't lose quality as much as on mine. I heard that these extenders don't suffer as much on primes than zooms. There seems to be consensus among this forum members that you get much better results with 1.4x than 2x. But would you want to spend that much money just to get 1.4x out of your 200mm?

I'm taking pictures of everything, so go ahead and take this place away from me.

Thanks! Canon publish the expected MTF performance for lenses with the extenders in "Eyes of EOS" book which is worth having.
