Nusach Maharitz is the nusach used by Dushinsky Chassidim, and it blends elements from Nusach Ashkenaz and Nusach Sefard almost equally, according to this Wikipedia article regarding N''S.
I am interested in obtaining such a siddur. Does anyone know where one could purchase one? (Online, of course.)
Also, in least priority, what is the history behind this nusach, and how close to N"A is it?
