Misty there is a difference between content providers and brokers.  Probably the 3 best known are RMP, DAZ and RDNA.  You also have Renderotica, YUR Digital, PoserWorld, Hivewire, Poser Addicts, Content Paradise, Poser Direct, On Target. Animotions and probably more sites that I can't remember off the top of my head.

What is it you are looking for?

I can't say RDNA is all that prudish.  They're located in Buffalo, New York.  Renderosity is south of the Mason-Dixon.  What's purdish about them?

I think you are mistaking those sites who don't want to have to deal with a limited number of credit management services as sites like 'rotica have to because they chose to sell content that is considered adult.
