Oops, my bad... That's what I get for using the windows calculator.... Still, the point is that only the core app is free. To get things like IK, shaders, deformers, etc, you will have to pony up $$$. If the functional equivalent of P4 is sufficient, that may make sense. But there is far too much implication about that DS is eqivalent to Poser (no version given, which leaves the uninformed to assume they mean the latest version), when feature-wise, the opposite is true.
