FWIW, I found the original listing for the Zunow, and that is a fair price, if straight.
From the photos, make double sure the fork isn't tweaked. Almost look like it has been in a light "front ender." Might also be evidence on the down tube and top tube. Look on the bottom side of each, near the head tube lugs, to see if there are circumferential paint cracks. Close your eyes, and run your fingers slowly over these regions too. What might not be obvious to the eye can often be felt. Good luck.
