Studio Maya has the Maya Doll, and there's a boatload of accessories for her..most are free..;) There was a 'lalala' character offered recently, and keep an eye on Daz..they have occasional free characters (have Sarah, but haven't found many clothes for her yet..and it creeps me out to have someone that young in a picture unclothed..sorry, but I have a 19-year-old daughter..changes yer perspective..;)
I think Mighty Lady has some characters, hasdrubal, and there's a plethora of robots out there.. go through freestuff, go to the 3d links forum and see if my links list is still there..I've got 400 poser sites in it for resources alone..good luck.

I wish I'd said that.. The Staircase Wit
