V 4.2 is one of the best female models out there, but is also one of the more complex ones to learn how to use properly.. you'll find tons of threads about using her in daz's various forums.

While it's a tad unclear now because of Daz Studio, Daz sells mostly poser content, and Daz Studio is their free application to allow people to test the waters using poser content.

So buying Daz's Poser/DS content is usually safe, they have a 30 day moneyback guarentee if you buy something that only works in ds (not much, mainly plugins), and thier platinum club gets you a bundle of goodies to play with, as well as some great ongoing  deals.

Way too many people take way too many things way too seriously.
