Sensors on the surface of the visor are tracked by a scanning unit so that head motions can be translated into in-game movement. While the Riftâs competitor, the HTC Vive, comes with VR peripherals, the Oculus Rift is just a headset, for now. Various iterations of the hardware have been in the hands of early adopters for a year or so now. Early versions of the rift only ran on low resolutions, and lacked full head head tracking capabilities.
1 Average total costs for a do-it-yourself installation of basin, pump, gravel and cement can run $150-$350. 2  Labor to replace an existing sump pump with a similar new model runs around $50-$150 or more. An average installation of a sump basin and pump (not including drains) runs about $250-$600 for parts and labor, depending on the quality of the equipment, ease of access and local rates.
Are you looking for a battery powered backup pump, or a backup (second pump) for your existing pump? I would expect to spend $500 to $800 for a really good battery powered backup system, or $250 to $500 for a second house-powered pump with alternating controls. That assumes that you have room for two pumps in your sump.
