eBay Game: Guess the Sell Price

So, I'm starting a new little game on +1lap, called Guess the Sell Price. I'll post a cyclocross item that's listed on eBay and in the comments, you guess what the final selling price will be (not including shipping).

This week its a Steelman frame, fork, Chris King Headset and stem.

Notice the track dropouts, perfect for a singlespeed or fixed gear.

My guess is $512.37
