I still can't get over how cute this is... (Resuggest, thanks to Jacob for the help!)

No Classified sellers at the moment.

SCM price seems to have vanished from the site? http://prntscr.com/9323ke ;_;

Extremely small Outpost market.

Recent sales:

http://www.tf2outpost.com/trade/27393932 Sold for a Smissmass Caribou, worth 37 keys (I think they count as pure so no overpay nessisary, tell me if I am wrong, they are easy to sell at 37 anyways :P) and three keys pure, thought the bp.tf histories don't line up on the Caribou and the Companions, but they were traded at the same time and the outpost seller of the Companions line up with the keys on backpack.tf http://backpack.tf/profiles/76561198068943237?time=1446883200&compare=1446969600 40 key final sale.

http://www.tf2outpost.com/trade/27337083 Sold for a MS Party Trick, updated at 38 keys, 35 keys after overpay

http://www.tf2outpost.com/trade/27415626 Sold for a Subatomic Head Full of Hot Air, unpriced, probably better to be used to price it, but has two sellers for 35 keys on it's Classifieds, so supports.

Sellers:

http://www.tf2outpost.com/trade/27391465 45 keys (Offered a Spellbound L'Inspector, outdated at 54 keys)

http://www.tf2outpost.com/trade/27398779 40 keys

http://www.tf2outpost.com/trade/27394977 "Around 35 keys", but only became tradeable today and already offered 35 and 36 pure)

Relatively wide range, but it is necessary, not a whole lot different from the first Strange AWP suggestion. After revisiting the sales, with sales at 40 and 35 keys, with such a small market, and SCM supporting, this should be alright to start.
