Buyer:

http://www.tf2outpost.com/trade/15421175 - Wants to 1:1 Haunted PY-40 Incinibot for a Macabre. I did some digging, and it seems that the PY-40 also has a wacky price range on Outpost. What I mean, is that there are sellers that price from 2 Ref (and maybe even less) all the way to 1 Key+. So, all in all, that would probably be a fair trade.
