I have about $2000 (US) available to spend on a 3d program that will give me very realistic renders of human figures.  I will only use the progarm to make static renders.  I am not interested in animation or modelling.

I am proficient with Poser 6, and have a huge library of DAZ and renderosity figures.  I intend to use these figures in my renders.  Ergo, the easier it is for me to import my posed Poser figures to the upper level rendering program, the better.

Which one would you advise?  Thank you.
