BoingBoing links to someone who’s selling his Pan Am Clipper model from the movie 2001. I still have this model, but without the viewable engine room part.
If you’re here in Toronto, I know of a small hole-in-the-wall shop over in Chinatown 2 (Gerrard and Broadview, north side of Gerrard, east of Broadview – sorry I don’t know the name) that is selling this model and a thwack of other great nostalgic sets, like the Space 1999 Moonbase model kit and a couple Big Daddy Roth’s Hotrod models. Save yourself the duty/shipping!
