8 month old price. I guess fishes love hydrogen borate and methanol. Just shortening up the range here.

Sellers:

http://www.tf2outpost.com/trade/17211239 - Offered a Roboactive Cyborg Stunt Helmet (2.7 Buds), but got rejected.

http://www.tf2outpost.com/trade/17439682 - Offered a Miami Nights Crocleather Slouth (3.4 Buds, probably an outlier), marked as C/O

Sold:

http://www.tf2outpost.com/trade/17348190 - Sold for a Stormy 13th Hour Jannisary Ketche. (2.3 Buds, unknown if sweets were added. Possible outlier.)

http://www.tf2outpost.com/trade/17362090 - Sold for a Ghosts Snaggle + 12 keys (Roughly 2 Buds + 18 keys/2.9 Buds)

http://www.tf2outpost.com/trade/13417864 - Sold for 60 keys(?) (Roughly 2.8 Buds back then).

Conclusion: Not too many sales on the market that are recorded. I'm setting the range to 2.8-2.9 because of the 2 sales that seem to be around the same price margin (since the Roboactive Stuntsman is 2.7 Buds, and that was rejected). Please provide counterproof if you find any.
