*"Is there some place I can download a free sample figure to mess around with, or will I need to buy my first one?" *Victoria 3.0 is pronbably the best, and most widely supported Poser character to date; but keep in mind that she(Like any DAZ figure) does not work with the Face Room(yet...)  Only EF's default P5, P6, and P7 characters do(plus the free Appolo Maximus figure)  You should weigh this fact before you get too invlved with either set.

FYI - WHile the base V3 is free, and you could could use Poser's Magnets with her, until your hearts content; the lion's share of her power(out of the box) is with her Head and Body Morph Pack, which is currently on sale at DAZ for %50 off, which I hav'nt seen in years.
