There is clearly a simulator better than About Golf. Full Swing Golf has the most accurate sim out there. I've been playing on them for close to 10 years now. Infrared light is simply a faster and more concise measurement of ball flight than cameras. Also, paying PGA TOUR money to be the "official" golf simulator is a joke. PGA TOUR has an official calendar and an official shoe horn, ha ha. Doesn't mean anything about quality. Plus, Full Swing's simulator starts at 40-45k for complete system, including install! I just speak for what I believe in. Make sure you look at them too.
