Over the years, the eBay online marketplace has proved to be the home of some pretty obscure and often bizarre things which have been snapped up by users all over the world at some pretty insane prices. Although, any seasoned eBay member will more than likely be used to coming across something a little out of the ordinary, it’s often the high-end of rather unique technology listings that tickle our fancy. One of those items came only last week with a member attempting to sell an original and unboxed original iPhone for $10,000, and now we have seen an Xbox Durango development kit shift for a cool $20,100.
