You got your link backwards. But, no doubt like many things on E-Bay, the price will go up towards the end of the auction. Often jumping significantly in the last few seconds of the auction.
Sometimes Dura Ace and Ultegra Hollowtech cranks come in at similar price points.
This forum is for things you have for sale. not for things you see online. Finding a crank on ebay from denmark with a broken link is pretty useless.
