If you want to spend your time immersed in a virtual world playing games, seeing loved ones or just relaxing -- then you have an important choice to make.

Oculus, Sony and HTC have all produced high-end virtual reality headsets that offer a more immersive experience. Unfortunately, that comes with a price tag.
