Amapi can do all the tricks in all the tutes available, whatever the 3D app used in a specific tute. Add Anim8or and you can get your Amapi models into Poser as OBJ. No, I'm not working for Eovia (the Amapi company), and there's plenty of great apps out there (I use TrueSpace because I'm a creature of habit). But Amapi is the only app that never needs help to do a modeling job - it never ceases to amaze me that you can get it for free! The best learning resource is free, too - this place ;o) Have fun.
