Posting these as a favour, I don't have a hand in these sales or anything, just helping out.
Effigy Miniatures sci-fi models. I thought these were OOP but was put in touch with the chap who bought the moulds and he's selling the figures through Ebay now.
http://www.ebay.com/sch/davidcfarr/m.html?_nkw=&_armrs=1&_ipg=&_from=There are three sets available or you can get them all in one bundle or just a set of all the female characters if you so desire. Shipping appears to be GSP outside the US but if you're looking to buy multiple lots drop him a line and I'm sure he can accommodate your order.
I painted a set for a client some time ago which prompted me to track them down.
