Resubmitting. I have literally no idea why my last suggestion on this would not pass with nearly a 95% upvote.

-Selling for 2.2 buds (rounded from 24 keys a bud), got an offer of 2 buds. Remains unsold.

Link 2: http://www.tf2outpost.com/trade/8235570

-Ignoring B/O, accepted offer of Burning Flames Sola Topi(Which was 50 keys at the time, or around two buds). After overpay, it's about 1.8buds. Owner of the pipe was too slow to get the offer.

-Best offer was an NNB Executioner (2-2.4 a month ago) a month ago. About 1.7-1.8 with overpay

Link 4: http://www.tf2outpost.com/trade/11046103

-Best offer of 1 bud+White bill's+Black Bill's+8 keys which, valuing those bill's at 9 keys, comes out to be around 2.1 buds.

-Best offer is an sf rocket launcher (1.9-2.1). Trade is one week old, please keep that in mind. This proof may or may not help or hinder my suggestion but I leave it there for you to decide.

-Best offer was a Bubbling Wraith Wrap(1.7-1.9 buds, 1.5-1.6 after overpay)

-Best offer was a Peace Sign Desert Maruader (1.7-2.1 buds, 1.6-1.7 after overpay)

Stolen proof from Sir Jon

http://www.tf2outpost.com/trade/11324059 sold 1:1 stormy bicorne (2.1 low end)

http://www.tf2outpost.com/trade/11259721 sold 1:1 blizz cannonball (2 low end)

http://www.tf2outpost.com/trade/11459013

http://www.tf2outpost.com/trade/11427987 seems to have 1:1 black level 1 max (2)

http://www.tf2outpost.com/trade/11504509 added something small for clean ts max (2.2)

That's about the best proof I could find not including new robo effects as their prices are extremely volatile currently. There was one person offering on nearly all pipe trades posting that he'd pay 2 buds. Keep in mind I used him in the first one and then not again for any.

Anyways, vote accordingly and please comment if you thing I need a new range or if I got something wrong or if you can find some good counter proof. Thank you!

KEEP IN MIND I STOLE PROOF FROM MY LAST SUGGESTION THAT WAS FOR 1.8-2.2. SOME OF MY PROOF STILL SUGGESTS THAT THE RANGE SHOULD BE DOWN TO 1.8 AND NOT 2. I'M TOO LAZY TO PICK IT APART FROM THE NEW SUGGESTED RANGE. DEAL WITH IT.
