Sales

http://www.tf2outpost.com/trade/13201111 - Kill-a-Watt Hat of Cards = 4.1 buds

http://www.tf2outpost.com/trade/13805677 - NnB Veil + 3 pure = 5.1 buds

http://www.tf2outpost.com/trade/13480697 - Chromatic 13th Hour Ketche + Smoking Phantom + SF Knife = 5.2 buds (I think)

Conclusion

Im not sure about the value of the Ketche in the 3rd sale, but Im pretty sure half of the spell's value is added onto it. If someone knows otherwise, please speaketh the truth! :3 For now, I guess this is ok.
