I've just purchased a PA 17-72 DNC and very happy with it - in my case the limiting factor was that most headsets press uncomfortably on my ears and becomes painful after even 45 minutes in the air. I knew the Pilot ones were OK (They are wider around the ear) as I was using a Pilot headset from the flying school's collection when it was available - lesson here I guess being don't buy a headset you haven't tried on.
Long term I may get a more expensive one and use the PA 17-72 for any passengers, but for now the money is going on basics like flying time rather than shiny kit!
