http://www.tf2outpost.com/trade/24382256 (sold for a knife, I can't price cs:go knifes for shit. If anyone wants to help it was a huntsman safari. But this will be an outlier but lets go. The cheapest on the market is $57.63 USD, minusing 15% is 48.9855, 48.98 is equivalent to 1.9 buds. This will support the 1.8-2 range (being 1.9) but cannot be a main proof.)
