There is a new OoW 2HB which is basically a dropable version of this. Called Stick of Fury. 50/41 100dd proc. Stats are a tad better on the stick and the 100dd proc makes up for the slight lack of damage ratio since GSo4W only has 75dd proc.
Also, SoF seems to be extremely common. Bought one on Tunare for 5k tonight. SoFW was still 35k and sucks compared to this.
