Just wondering if any one has had a chance to peruse this publication yet?

BMW R1200 Dohc Air-Cooled Service & Repair Manual: 2010-2012. Phil Mather (Haynes Service & Repair Manual).

I searched and found zilch in the R1200 forum (hexhead/camheads-why do we need 2 names?). For $42 at the door, is it more useful at half the price, than the BMW CD? I do plan on getting the BMW CD someday-if I need it???

Does someone have both and can issue an opinion?
