I wouldn't worry about this end of the market - too many hobbyists that shop here appear to be aggressively unwilling to move beyond a Poser 6 flow.  That applies even moreso with the vendors.

More accurately, vendors are aggressively interested in making money, and that means building content for figures that people actually want to use, that are designed properly and don't contain missing faces or holes in their mesh, or overlapping UV maps, or geometry that was never mapped to begin with, or a-symmetrical inconsistencies that make much of their content construction a nightmare or simply impossible to do. If you're not a content artist then you won't understand this until you actually dig in and learn the process and the differences. 

For example, P6 James is my favorite figure, but he is unusable to me as-is. I've had to rebuild him just to make him viable as a figure, and there's no point in me wasting my time doing all that because I can build my own figure with less headache, and do whatever I want with the end results. Give it away, sell it, whatever, because its my figure and not someone else's mess that I've had to clean up and rebuild because they clearly didn't know what they were doing to begin with, or didn't bother paying attention to details. 

And that is basically the case with all the poser natives. Slapped together as an afterthought with no real quality assurance. When the majority of users have to modify the content just to get it to function the way it should have out of the box, they're just going to find someone else's models that are easier to use and better constructed. Or build their own, as I have.
