I only have a 6 x 5 ft play area, not much for room scale, but I still want a 3rd sensor so I can reach behind me still.
A word of warning for people getting the Rift: You might not have compatible USB ports. I'm not sure about the latest motherboards, but older ones like Z97, X99, etc come with incompatible USB ports using Etron or Asmedia USB controllers. You have to only use the Intel USB ports on those motherboards, which typically either come with 2 or 4 Intel 3.0 ports in the rear.
If you dont have enough USB 3.0 ports, you can get an USB PCI-E card recommended by Oculus:

Lol, the price on both versions have gone up by $3 in the last day or so, I guess it is all the new people getting Rifts. I'm going to try the 4 Intel USB 3.0 ports included on my motherboard first and see how that goes.
