I've gotta admit, I got on the waitlist for the Ex. because. . .it is exclusive. I don't like the Ex. head and only want the regular version for display. But, they cost the same on Sideshow's site, plus Sideshow's customer service and 5% back via reward points makes it a better route than buying from other retailers.
So I guess, for me, that I'll go with an Ex. I've got no use for. . .holding all other things constant. Because at least if I sell it down the road, it's then worth a few bucks more. I supposed edition size plays some role in that, as well, though I can't imagine I would ever use edition size as a key factor in my decision-making calculus when deciding to buy something or not. For me, that kind of thing matters on the margins.
