The median asking price for a used one is $73.79, across 22 live eBay listings for the 2000–2006 generation. That is what sellers are asking, not what buyers paid. Sold prices are not published in a form anyone can measure at scale, and an ask read as a sale runs about a quarter high — so this says which one it is.
