Your proof doesn't support your range and I would have given you more then that myself if it was clean

You're going to have to prove it. Please make sure you read the rules regarding making a suggestion, you need valid sale proofs in order to suggest a price.

I guess you do have 1 bud + 3 keys as new items, but still, since when does 1 bud + 3 keys = 1.5-2.2 buds?

Yours was gifted and the clean one was offered just under 3 buds. http://www.tf2outpost.com/trade/13605401

Plus you need to have atleast 2 sells to price a new unusual anyway.
