Forgot to add two sales last time this was suggested, so let's go:

Sale 1: http://www.tf2outpost.com/trade/21628894#latest

Sold for: C. heart engie cap (2) + C. heart Kabuto (4.5) + FoD Square Dance (5.2) + S. killstreak Aussie wrench (1.25(Kit is only worth about a key)) + Pro ks Aussie Frontier (1 bud (based on market sales, may or may not be wrong)) * 0.9 = 12.5 buds

Sale 2: http://i.imgur.com/PvrtRXU.jpg?1

Sold for 12.5 buds pure

Sale 3: http://www.tf2outpost.com/trade/21237701

Sold for a burning Katsyusha (?) + 6 buds

Unfortunately this is a 1:1 hat and has only been sold once, which was in this trade

Can't provide a mini suggestion because of that, but might as well mention the trade because of the pure

These are pretty difficult to find sales due to very little being on the market, any suggestions are welcome,
