If beefy PC → Vive Pro is the one we mostly use. It can could be extended to have full body tracking. But if you don't mind giving Facebook your money, then the Oculus Quest 2 is very affordable. You can even cast games wirelessly from a PC I bought an Index a few months ago, which is a tad on the expensive side if you're just getting into VR, but it does offer good resolution and is quite comfortable
