The cheapest option currently starts at $44.99, while premium listings can reach $8276.99 — giving you a wide budget spread to work with. The average price of $740.27 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.

For used items, look closely at the condition description and photos — terms like "good", "very good" and "like new" can mean very different things depending on the seller.
