as another typical aviation ripoff: Take the normal price you'd

multiply by 10 to get the actual price because it's for an

What do you think it costs to build 100 units vs. 20000 units that

This "economy of scale" argument doesn't always explain the perceived
excess in price. Some things in aviation really are ripoffs. Sort of
like the saying: "Just because you're paranoid doesn't mean they're not
really out to get you".
