5 months old, time for an update.

Sales:

[url]http://www.tf2outpost.com/trade/24065262[/url] Sold with a TW Tough Guy's Toque for a Max's Head 3 days ago.

3.3 (max's head) - 1.3 (recently updated price of the toque) = 2 earbuds pure

[url]http://www.tf2outpost.com/trade/24100245[/url] Sold for 25 keys pure a day ago.

25/13.25 = 1.88 buds rounded to 1.9 earbuds pure

[url]http://www.tf2outpost.com/trade/23283594[/url] Sold for a vivid plasma hotdogger a month ago.

It's outdated by 2 years, but it's priced at 2-2.2, so after overpay it lands at 1.89 buds, which I would round to the low end.

Can't find anything to prove that it's worth that, but I don't think it hurts to include this sale.

[url]http://www.tf2outpost.com/trade/22949460[/url] Sold for a Skill Gotten Gains Spent Well Spirits about 2 months ago.

Another outdated one, priced 5 months ago. It's priced at 2.2 buds though, and after overpay that equals 1.98, or about 2 buds.

I have nothing to mini with for it, once again, except for an offer of an outdatedly-priced Aces Chieftains worth ~2.25, which kinda supports it. Again, take it at face value, probably doesn't hurt since I have my other sales to back up the values.

Offers:

[url]http://www.tf2outpost.com/trade/23805868[/url] Someone offered "Tower 2.3" 5 days ago, offered the buyout on all but one of the hats in the trade, might not be legit.

[url]http://www.tf2outpost.com/trade/22502547[/url] Blizz Full Metal Drill Hat + Bill's ~2 months ago.

1.75 (recently updated Drill Hat price) * 0.9 = 1.575 + (5.75 / 17 = 0.34, prices of bills and earbuds at the time) = 1.915 rounded to 1.9 buds

Got a good sale, unreliable sale, and random offer for the low end, got a good sale and an unreliable sale for the high end, and got a big, fat, possibly illegitimate outlier. Also got a lot of offers of 2 bud hats that are too low after overpay so I don't care about listing them. More proof is always appreciated.
