Kingdom Death (http://kingdomdeath.com), makers of all things beautifully sculpted and profoundly NSFW, have released a 54mm version of one of their more "subdued" figures.

At $40 (http://shop.kingdomdeath.com/product/54mm-twilight-knight-pinup), she's a fair low price by Kingdom Deaths standards.
At 57mm to the eyes she'd be quite amazonian compared to most Inquisitor models, although if you're after a female feral worlder she may well be just the ticket.
