Yeah, I'm quite fearful of the costs as well, and off the top of my head, I may guess around $250 per piece ($1,000 total). But I think a greater cause for concern is going to be space. These things are MASSIVE. I have no freaking clue where I could put the both of these. Certainly not in my collection room...
Damned beautiful though - both of them. And dammit, if they do the Cantina and Jabba's Palace next, I'll totally wet myself.
Another huge dilemna with these sets, is whether to actually collect the metal figures as well? ****. I dunno. I want them as dioramas for the 4" Hasbro line, but I just know that I'm not going to be able to pass on the corresponding Attakus figures, lest the sets aren't "complete" (yeah, shut up!)
I'd likely get the figures too, and wind up displaying them separately elsewhere. Wonder what they'll run... Maybe about $20 each?
