There should be a listing for the base stations too. You can buy more individually to extend the range of your playspace, up to 4 base stations I think, or if you want to upgrade from vive 1.0 base stations piecewise. Not that while the index headset and controllers are backwards compatible with 1.0 base stations, the vive headset isn't forwards compatible with the 2.0 base stations.
