Ok so just to update, I signed up for the Microsoft mixed reality Steam VR beta, and got my key yesterday.
straight into Elite and.... WOW gives you a real sense of scale sitting on the pad inside a station.. being able to look around the cockpit was also cool, I had to lean to "see" past the back of my chair, while i was looking back and leaning in my actual chair felt like I was there!
of course not everything is roses, it seems to take a long time from startup till ready to fly and had a couple of crashes, but to be expected as it's still in beta.
For this reason I was too scared to try flying my cutter so brought a cobra in case i prang it in the slot ;-) will just practice flying it around till I get used to the headset.
This is my first VR headset I have owned, and I would recommend if you are thinking of getting one to definitely try one out first if possible. it has taken me a while to get used to it and using it properly, i.e. turning my head to look instead of moving my eyes.
In case you don't know because of the lenses the focused area is directly in front if you use your eyes to look to the sides it's blurry.
And took some juggling to get the headset on in the correct place with my glasses on, but once on and adjusted no issues with them. I have the acer headset, so not sure about the fit of the other brands.
