I'd probably just pick up a OSVRHK2
but I'd need to connect to a computer. Otherwise it sounds like I'll wait until it's really cheap or I find a nice deal.
I still remember the NES "VR" I used to own. It was a 8lb tv strapped to your head with a neck brace harness so you didn't fall over. They even marketed it as NES VR, but it was simply a portable tv display in goggles with av cables that plugged into anything.
