I found these at a flea market for about $2.50 each. I'm pretty excited to have found them. It seems the right Flea Market can offer better stuff for me than freaking Ebay! Anyway, as it turns out the first two figures in the pic are apparently rather rare, which is why I was excited to see them in that giant ash tray with the thick scent of old cigarettes and lung cancer called a market. To give you a better idea of why here's a couple of links.

The woman figure is Ripley from Aliens, the only woman in my collection of Kenner made figures other than Princess Leia, but I hope to change that by getting Ellie Sattler and Sarah Harding and maybe even the woman from the movie Congo. Something I find interesting about Ripley is that the over sized rocket launcher that comes with ROC destro fits perfectly in Ripley's and Alan Grant's hands. By chance I have two of those launchers. They are now rocket pals.
