The NVIDIA Shield TV is on sale for $149.00. This price matches the lowest price that it has ever been. This is the bundle that includes only a remote and does not include a game controller. The bundle with a game controller is not currently on sale. The Shield TV runs Android TV and is a good alternative to the Fire TV if you need the extra horsepower for tasks other than watching videos, like playing PC caliber games and running a local Plex server on the device itself.
B&H has the same Shield TV bundle for $143.20
