Can't comment too much on the VOTC one here, since I've only found one and he's staying incarcerated in plastic until a second shows. In terms of VOTC appropriateness, I think he's actually really necessary. A lot more than say, 3P0. For characters closely tied to ESB in think Yoda, Lando, and Fett. It seems like they're 12 figure limitation screws up the whole idea of VOTC, putting essential characters on their vintage cards. I think the Emperor and a Biker Scout are very ROTJ iconic, and there's just no room for those guys. We need a second series of these suckas.
But anyway, I love the OTC Yoda to death. It pretty much does everything I need out of Yoda - he cleverly separates to fit into the backpack and has articulation at the shoulders and neck that allow him to look right leaning on his cane or conversing with Luke from the pack. Excellent figure.
