I've just had a little first time play with rendering using the free version of DAZ Studio, and like it enough to consider buying a full-blown rendering prog. But which??

I'm looking at Poser 8 now, and am concerned about the negative comments applying to Poser 8 and my Mac 10.5.8 system.

Can anyone tell me why e-frontier's Poser 7 is so much more expensive than SmithMicro's Poser 8?
