My point (which I didn't explain that well) is that 'desirability to 
collectors' is almost certainly the main factor in the price. I think 
that 'rarity' may well be a factor in 'desirability to collectors' (some 
collectors will want to have a machine that nobody else owns), but may 
not be the main factor.
