Welcome back! The figure that seems to be most popular judging by the Marketplace is Genesis 3/Victoria 7 which is DAZ Studio only. You might want to start from there since that program is free and most of the vendors have shifted to character and clothing creation exclusively for her. The Victoria 4 stuff is now few and far between but that might mean there's less competition too. But if you haven't already got Vicki4 I don't think now would be a good time to invest in her.

Another solution might be to contact Erogenesis about his upcoming figure Project E. He's said he's hoping for a summer release and that would give you time to catch up with Poser (if you're sticking with that). You can read more about her here and at RDNA
