I started with a magazine freebie of Poser 3, and then jumped to Poser 5. And was intimidated by the Firefly rendering engine for a long time. But it does have the p4 render engine as well. Right now, I'd say Poser 5 (with SR4) is the way to go. I wouldn't take a chance on P6 until I hear from serious users who have been using it long enough to get past the goshwowoboyoboy phase.
