I've got a HTC vive headset/controllers/lightstations, but the controllers are fucking up and I've heard Valve's Knuckle Index controllers are really good, however i'm australian so buying anything index related is very expensive.

Is the Index headset itself much better than the standard Vive's? Do you think it would be worth shelling out extra for a headset+controllers set or is the better headset quality marginal enough that I should just grab the controllers?
