Okay, hear me out, there aren't many of these hats in unusual form. Usually, this effect is higher than Kill-a-watt, yes? http://backpack.tf/unusuals/Frontier%20Djustice The Kill-a-watt version has a price of 3.2 buds. Seeing as though there are less of this hat with the Cloud 9 effect ( usually more expensive in almost every unusual ), I'd see that the price range should fall between 4 and 5 buds. This hat has received offers from this price range in the past with old owners: http://www.tf2outpost.com/trade/22423714, http://www.tf2outpost.com/trade/21631424, http://www.tf2outpost.com/trade/22567698 . One of the offers that sticks out to me is in the middle (2nd) trade on outpost. It has received an offer of a Harvest Moon Bonk Helm which is worth 4.4-4.6 buds (~4.5 buds) http://backpack.tf/unusuals/Bonk%20Helm and one on outpost is asking for 5 buds, while the other is looking for offers: http://www.tf2outpost.com/search/227173967 I hope this is plentiful proof, thanks for reading/ voting, and have a nice day!
