Asking where I know there are lots of skills and knowledge.
I was thinking about getting a 2x (ii or iii) extender to use with my 5D ii and or 7D and 70-200 2.8 IS.
Is that a bad idea? Will I lose to much quality compared to a 100-400?

The 2X doesn't get a lot of praise, but the 1.4 does well (these are Version III). I have the 1.4 and saw some video work my son did using it with the 70-200 f2.8ll on a Canon C100 video camera. The video was terrific!

Thank you for your comments. I stay away from those converters and wait until I can afford another lens that will cover up my needs.

A f/2.8 lens becomes a f/5.6 lens with a 2x converter (if it fits) attached, so the combination will work fine on most all bodies.
The 100-400 is a f/4.5-5.6 lens itself, so same/same as far as aperture is concerned.
But I have never been happy with the resulting image quality using a 2x converter, I can usually see noticeable degradation.
As mentioned the 1.4x on the other hand is terrific.

I have seldom seen a review of a 2x TC that is good. I think you can essentially generalize that you are insane to use a 2x TC (I exaggerate, but only a little). I recently got a Canon 1.4 TC (a version II), hoping it would give good results with my Canon 400mm 5.6 and new 80D. So far I like what I am seeing, which is a little surprising to me. I should think that it might work pretty well with your 70-200. I got my 1.4 second-hand on the KEH used equipment website at a really good price. I recommend checking it out.

Having owned the Canon 2x TC, the 1.4 TC and the Kenko 1.4 TC and used them on a 70-200 L and other lenses I can say the Canon 1.4 TC is the best option, as the 2x looses quite a lot in image quality.
The loss in quality compared to using the 100-400 mm IS L MK II is huge, so much so I sold all my TC's.

I also used a Kenko 1.4 TC (a Pro DGX model) - I used it with my 400 5.6L and my older 60D. The Kenko is special in that it fools the camera into thinking it has max aperture > f8, to preserve AF on a 60D; this is no longer necessary on the 80D, which allows center-point AF even at f8. The Kenko focuses pretty well, but the IQ loss was more than I liked and I stopped using it. So far I like what I am getting from the Canon 1.4II and the 400 5.6.
