Hexagon is the way to go for organic modeling and character models. I just bought version 1.2 with the free update to version 2 coming in April. The new version looks amazing! I was thinking I would have to pay $500 eventually for Z Brush for it's cool displacement mapping brushes, but Hexagon will offer similar tools for a fraction of the cost. Plus the benifits of UV mapping/unwrapping for texture maps rather than importing to Carrara to do the UV mapping. You can always upgrade to Pro later, but I think Hexagon is the best bang for the buck right now.
