Fixing the price a little. Last price suggestion had a lot of proof, but the price range went too low: http://backpack.tf/vote/id/519cdc834bd7b8b147000013

The proof that vortex offered showed multiple offers of Max's Heads and other 2.2 to 2.4 bud offers, but the lower bound was put at 1.9 buds for some reason. It's so easy to find offers at 2.2 buds that anything less shouldn't be within the price range.

Proof, all within the past week:

Max's Head + >10 keys in sweets = 2.7 buds

Max's Head = 2.3 buds

http://www.tf2outpost.com/trade/10852668

Max's Head = 2.3 buds

2 buds + 5 keys = 2.2 buds

53 keys = 2.2 buds

2 buds + Bills + 3.5 keys = 2.5 buds
