Two exist, both for sale:

http://www.tf2outpost.com/trade/19223246 - "Quick sell" at 30 keys, he claims it to be 50% off... not sure about that.

> Bought it off a sharker... no record of trade. :/

> Offered a burning bandana with Kill-a-Watt, which according to backpack.tf don't exist.

http://www.tf2outpost.com/trade/18557563 - Selling as a set, I think. Offered 2 buds. Wants 3.

> No other owners, so no solds.

So, we have an offer of 2 buds pure + sweets on one, and one is selling for 30 keys. Is it reasonable about to go from 1.5 to 2 buds then?
