Yup, that's the price as a collectors item, but also as a spare part for devices that can be sold at thousands quids once repaired, so if the price was based purely on demand over offer it would still make sense. Whoever had the idea is a genius to me.
That's insane. Those are manufactured for at most $20 (assuming tiny quantities), and even if you lost all the original design files reproducing them isn't that expensive.
