3D VR Headset(s)

Has anyone owned or tried one? There are so many out there. Oculus Rift has had a big name in VR and VR games, as well as Sony. What’s the experience worth to you in terms of money? How much would you pay for one?

Oculus Rift has finally gone past the Developer Kit stage,and the public version is on sale for $599
Sony HMZ-T2/T3 are similar, except that they can convert media on a microsd card which plugs into the headset, into 3D Theater experience. New ones range from $700-$1100, while ebay has some pre-owned one going for $350+.

Please share your thoughts.
