Re: Real Question
How do you know how much money they are 'wasting'?
The only 'gaming' kit (as mentioned in the article) I'm aware of that can do this, was from 10+ years ago, the Gforce/nVidia 3D Vision glasses, even if it was bought new at the time, you'd still only be talking a few hundred dollars or so. All they are is a set of active shutter glasses (same as you'd get with an active TV set), and a small USB IR transmitter to help with the timing.
Tie that in with a mid range nVidia GFX card and a 120Hz+ monitor (works with CRTs as well), and you're good to go. Even a recent mid range Laptop could do this.
