Sideshow had announced, I believe, a year ago that they were going to make full size statues of R2-D2 and C-3PO. They now have the design approved and threw up some pictures and an order for them both. http://www.sideshowtoy.com/?page_id=4489&sku=2215 Anyone got 5k?
They are crazy expensive, and building your own would probably cost you less, but damn, talk about the ultimate collectible.
Actually, building your own Artoo unit is not only cheaper, but it'd actually work, too (movement, lights, sound - not just a statue). I've always wanted to sign up for one of those courses...
