It's on its way, Dwmdesigner.

I use MilkShape 3D, a low-poly shareware modeller originally designed for game (Half-Life) development. It doesn't do splines and advanced stuff, but for $20 it's a steal, especially considering all of the file formats it supports.

By the way, I'm still tinkering with my Arnold morph for the Poser Male. You can see a couple of pics of the work-in-progress here.
