NN/g report and its application in design

Just wondering if anyone has had the experience of purchasing a NN/g report, which seems to be an authoritative and often quoted reference for things UX and web design related.

I am trying to justify the cost of spending money on the report instead of actual user research (i.e. no budget), but I was wondering how much of the research is general insights versus specific and actionable recommendations that you can apply directly and then test and customize for your own specific situation.

If the NN/g report is not suitable for use in this situation, is there any other research that can be purchased which will?
