The cheapest option currently starts at €3.95, while premium listings can reach €2499 — giving you a wide budget spread to work with. The average price of €106.63 can serve as a useful benchmark: listings below this tend to be used or auction-style, while those above often include extra accessories, warranties, or are sold by professional sellers with high feedback scores.
