Dan Bishop from Karas Kustoms makes and sells these beautiful machined aluminum speedsters for $65: "It measures approx. 6″ x 4″. The wheels are mounted on bearings and actually roll. Each car is machined from 6061 alum, in our shop, right here in the good ol' USA."
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
