I've got no problems.
I like the GoLean, stuff except that it's too crunchy unless it's soaked in the milk for awhile. Otherwise, I end up making a pained face when I bite down on the really hard crunches.
My issue when I went through my cereal phase wasn't the cereal choices, but the milk. I switched to almond milk and that ended those problems.
I agree with Brad about the original Kashi. It is delicious, but only with more sugar poured on it than you'd get with the good kid's cereal. Same deal with plain cheerio's.
