I havnt heard about a special version for artists. :/
Ive have Poser 3 (is it up to number 5 now?). The Poser gets better and better all the time, and theres plug-ins for even better bodies and stuff, hair seems to faschinate people very much:
However I think the poser program in general is a bit "stiff" and cannot be used so good for references, except of maybe rough drafts for poses. When it comes to more lively things, the posermodel, well its a manikin of sorts. It lacks "life" its very stiff.
I sometimes use it for templates though - U can make one pose and turn it, that makes a good template of the same guy in different angle.
I would go for a digital camera and a friend instead of Poser for references...
