Yogurt

What's your favorite no-sugar-added active culture yogurt?

Dannon Light & Fit has a bitter taste to it, although that might be just the one flavor I've tried so far. (I also seem to taste bitterness unusually strongly. I can't put broccoli stems in my mouth, and there's no way I'll ever like coffee.) But just about everything else in my local supermarket has so much sugar in it that I might as well eat a candy bar.

Recommendations?

[edit: Wow, you guys are great! I've got a big pile of good ideas already!]
