Mostly placing this here for posterity's sake, but here is my first unusual suggestion:

I recently sold mine for 3 buds 6 keys pure:

This guy's trade has been up for 3 weeks. Offered 3 buds at one point but no response.

Here's a good one:

Sold to http://lv3.backpack.tf/profiles/76561198025083656?time=1420790400

Looks like it was sold for 3 buds around January 9th: http://lv3.backpack.tf/profiles/76561198041982677?time=1420790400

Another one, somewhat puzzling:

Selling for a mere 2 buds: http://www.tf2outpost.com/trade/24622834

Possibly because it's duplicated?

Scooty Puff Jr. http://backpack.tf/u/76561198028366833

Only seems to have had it for a day or less.

Looks he bought it from this user: http://backpack.tf/profiles/76561198074313318?time=1421049600

Whom, in that period, he lost an eerie orb fire Pith Helmet and the orb fire Rack, and gained a TS Max and Circling Heart Drill Hat.

Not quite sure what to make of that last one, but I've settled on this price range. Most people seem to not want to sell below 3 buds.

Any additional insight or advice is appreciated!
