http://www.tf2outpost.com/trade/16082252 (1 bud, see this trade: http://www.tf2outpost.com/trade/16100631 and click on fourth from bottom post. That guy said he bought one for 1 bud, and he has that Brigade Helm now. However, he offered 1 bud + 3 keys = ~20 keys.)

Wolf Hound also offered 22 keys, and "I got Hacked" (probably not real name) said he would do 1 bud + 7 keys (small outlier). I was also willing to pay 1 bud + 4 keys, but bought another Unusual instead at a great price, otherwise, I would have bought it at 1 bud + 4 keys.

http://www.tf2outpost.com/trade/16090680 (Offered 22 keys, accepted, but somehow deal did not go through). I also offered my Stormy Attendant 1:1, but mainly because I bought it at a good price, and I want a Blizz Brigade instead. Last update on the Attendant was 1.3-1.5 buds, multiply by 0.9 gives ~1.2 range on the Brigade, and he did not reply (we actually traded, the real owner didn't have anything to add so I told him that I could 1:1 for now and he could pay me back 2-3 keys later when he gets pure. We made the trade, but then he traded back as he said he would rather not be "in debt", and he'd rather make the trade all at once).

http://www.tf2outpost.com/trade/16312800 Unsold, but was offered 22 keys, and 1 bud + sweets, and 1.1 buds (BMOC + 4 keys).

All in all, I'm setting a high range at 1.3 buds (Sale at 22 keys, and a few offers/sales at 1.2 buds, but that's close enough to 1.3). The low range is 1 bud, as that was the lowest sale.

Feel free to comment or whatever with constructive remarks. Thanks.
