DING, DING, DING......Expensive.....What do I win???
Auction price is different from a routed dealer/retailer. Everyone always gets pissy when I say 3600 or 3800 at auction....Of course, you could have the HUO one that's currently for sale right now for 12,500. I'm not going to play price police there as that's a valid amount in a collectors market with the stupid prices things are going for right now.
So the correct answer is as cheap as you can find one with the wear that you find acceptable.... Sooooo, somewhere between 3600-12,500.
