I finally bought it. I'd had my eye on it for months. The backdrop tool is easy to use, and I'm grateful for the additional, free, backdrops provided by greybro(!?) I may need to fiddle a bit more with lighting, whatever... but it is nice that Nerd also included light sets! Wow.. This is much better than putting someone in front of a flat background and pretending it looks good. (The image quality isn't as good as it could be since Renderosity now complains if the filesize is over 200K. I need to save for the web, and reduce the picture size. But maybe you get the idea?!)
