I've seen various 12 inch scale X-Wing's before on eBay but this one is definately the most impressive so far.
I can see the high price (must have been a ton of work), but where on EARTH would you find room for it!?!
*Most impressive thing I've seen is still the huge diorama of the Imperial Shuttlecraft docking in the Death Star from Celebration III. I just couldn't believe how large it was in person!*
