I hope you sell it. That said, this forum is not a re-post service for eBay auctions. State a price in BTC and remove link. Also, are you nuts? $4K?
You do realize this is second batch, and is almost half price. No, it's extremely reasonable, as it's best out there. Also price in BTC, would be $5400 USD going price in BTC. Reputable escrow will be used.
