what do YOU suggest?

I can assure you that there is no tutorials for making bodies and heads... If you are looking into character modelling, there IS no best program, I can't stress this enough, it's not the tool, it's the artist. I don't care what you work with. As for the bodies and heads I suggest you get very familiar with modelling in general, and venture on your own, so far I have yet to see a good complete character modelling tutorial.
