Overview of Trichotomous vs Dichotomous views of Man

There are generally two* views of Man - the Dichotomous (Soul & Body) - the Trichotomous (Soul, Spirit, & Body) Notably, [A W Pink](https://christianity.stackexchange.com/q/6870/69) ascribes to the Trichotomous view (or Tripartite). Also notably, [R C Sproul](http://books.google.com/books?id=DC-TRU4tEvsC&lpg=PT156&ots=TvaN8tCFza&dq=r%20c%20sproul%20trichotomous&pg=PT156#v=onepage&q=r%20c%20sproul%20trichotomous&f=false) views the Trichotomy as heretical. Personally, I believe that the [Platonic](http://en.wikipedia.org/wiki/Plato) Tripartite view is dangerous or heretical, but the Bible does seem to indicate at least some type of trinitarian mirroring of the image of God in Man. What is an overview of these two perspectives and how much support is found in the Bible for both? ---- *An argument can be made for a Quadrichotomous view (Body, Soul, Mind, Spirit), but can be covered in another question
