Even you, seems to be confused with the price. So how much really it is? Anyway, what is your reason of selling? If a person can sell it for $1,000 or even $10,000 as you have mentioned here or $15,000 as stated in the title, why don't you sell it yourself with that price? Something's wrong with that, right? Very unusual for people to sell a thing in a very cheap price and let others earn from it.
