[Cronos]

I wouldn't call Manichaenism a Heresy -- it looks more like a highly syncretic religion. It took aspects of Gnosticism (which WAS a Christian heresy) and added in Zoroastrianism, Buddhism, etc. etc.

Also, I wouldn't say Arianism was a "more tolerant form" -- Arianism is similar to what the Jehovah's witnesses now believe, namely that Jesus is a "lesser" god, not of the same substance as the Father.
