this is getting more popular as a cheap strange and seeing as the only thing which comes close to it is 5 keys now, this has become a very popular weapon, i found it hard to buy for 1.55, let alone for 1.33, in the end I bought 1 for a 2.33 ref strange. Also seeing as most sellers are selling at 1.66, none lower, then that should be mid range price not max, proof:
