So from what I see the three options I have at the moment are
1) Facetracknoir - cheapest, only requires a webcam
2) Freetrack - second cheapest, requires a webcam and some kind of IR/LED trackers, usually on a hat or glasses it seems.
3) TrackIR - Most expensive, but looks straightforward in use.
Looking for feedback from people who have used any of these (or another) and there recommendations.
Thanks!
