I would assume most people would buy 2 (if they had an Emperor or Vader already). It would have been cool for SSC to give a discount if you bought two (like 5-10% off the total).
Yes, the suit just doesn't look right. I am not a fan of mixed media and I think this would have been better without it. On the plus side, I personally think the headsculpt looks great.
Pass. Not that big of a fan of the character and I have limited space. With that being said, I think this statue looks good (and better than SSC's last effort).
