If you're not ready to splash out on an Oculus, or even Samsung Gear, I started using one of the smartphone headsets. £20, slide your phone into it and with a bit of cheapoware called Trinus VR you get the full experience.
It also spoofs the Track IR protocol and uses the gryos in the phone to track head movements. It blew me away, completely changed the way I use x-plane.

There are a few youtube vids around with a walk through, took me about 10 mins to get setup.
