You can pick up one of the rarest Nikon F's in existence for free; the only catch is that it's on the moon ... Hasselblad advertised something similar a few years ago, but the Nikon F's that the Apollo astronauts brought there were just as rare and rugged as those 'blads.
The later professional bodies were also featured on space missions, and I've seen pictures of the space shuttle version of the F3: very purposeful and massive; probably easy to operate with gloves on.
