And some other trades but I think that is enough.

http://www.tf2outpost.com/trade/7529086 - b/o of 2.8 (can't tell if young)

http://www.tf2outpost.com/trade/8788179 - b/o of 3 (young)

As you can see many trades happen in the current range, even if some b/os are lower and high pure offers are rare. Bumping the high end a tad down to get 3 buds as a average value + reconfirming infinite old price.
