That mega VR stuff is surprissinglly affordable. You could build a computer that could run vr the best it could for arround 2k, the top vr equipment is 1k, and add 0.5 for peripherals. A total of 3.5k against the 8.3 of that. It´s expensive, but having in mind that he will base his life around it for 5 years its not bad.
