While doing some post-processing research, I managed to come across this: http://iryoku.com/smaa/
It works extremely well on a sub-pixel level, better than any other type of AA shader I've seen.
And the best news is that it comes as a fully documented open-source project.

Has anyone seen a better looking, cost-efficient AA shader that works on a subpixel level like this one does?

MLAA + MSAA

Taken from their front page:
"Our method shows for the first time how to combine morphological antialiasing (MLAA) with additional multi/supersampling strategies (MSAA, SSAA) for accurate subpixel features, and how to couple it with temporal reprojection"

So SMAA is already a combination of those. Of course, it would probably be easier on the GPU/CPU to just use MSAA, but judging from the comparison charts in their PDF documentation, their method seems to produce even better results.
