Total cost over $200.00 
It is a little better than my TrackIR2 as far as sensitivity. Actually I had spent about 30 minutes turning down the sensitivities and getting it close to how I want it.
It's still a little touchy though. If I'm not carefull, it freaks out and shows me a view of the bottom of my seat.
Was it worth $200, not sure yet. It doesn't make approaches any easier but I can now find the hold short line in a 747.
I'll keep you posted.
