$52 off the normal retail price for this relatively newly released VR headset.
Better than Windows Mixed Reality headsets for playing games due to the additional inside-out sensors for improved tracking volume, and the ergonomic and easy to use Touch controllers. Worse than the Valve Index (Knuckles & Base Stations 2.0 are best in class IMO), but that's gonna cost twice as much ($999 USD). Can make an argument for inside-out tracking with convenience if you plan to move your gameplay area a lot (taking to a friend's house, changing rooms within the house, etc.)
Also consider the Quest which isn't on sale but can be used with Virtual Desktop to be used as a headset wirelessly
