Only bit of advice I would give, is to test out all 3 headsets, and throw in the GearVR if you can. Motion sickness and nausea are very real if the VR is done badly and head tracking not the very best. On lower powered systems and with less FPS I would be wary of investing my money until I know which one works properly for me. This will be our first retail consumer experiences and it needs to go well. Or, I can imagine the forum posts blaming VR rather than blaming the implementation of VR.
