Yeah, he's pretty awesome. He was actually one of my favorite vintage figures - probably because he was so tough to find back in 1978. I vividly remember finding him at our local Kmart. They had one of those figure header boxes back behind the customer service counter because the demand was so high. I remember seeing it when I was walking out of the store disappointed that there weren't any figures in the toy department only to see the box and this guy right there in the front.
Mike, did you get your R2 yet?
