As for the DSD, I got him with the same mass purchase of the entire set of new ANH figures as a kid, so I probably never gave him much thought. One of my favorite things to play was Jawa Droid Sale, though, and he was always there. And he hung out in the Death Star, too, I think he ran the elevator or something.
I don't have that BAD version...obviously didn't get that wave, even though I would like the figure, so oh well. Maybe someday Hasbro will make big Droid Factory sets of the pieces or something. Or maybe in a few years ebay will be the answer.
I am happy with the black POTF2 version (The real DSD anyway, IMO) and I like the Sandcrawler version a lot to cover my other memories. And I really like that Clone Wars version, too.
