My first post!! When my son went off to college, I set up a P3ProSwing in his bedroom. The whole nine yards. Impact screen, projection tv, dedicated computer, etc. It is a useful tool for swing analysis, club head speed, club head position at impact, etc.
It gives lots of useful information, but is a lousy golf simulator. Even when used with Tiger Woods EA sports game it's pretty lame. I use it mainly to warm up before a round (I hate the driving range) and if it's raining or cold and just want to hit a few balls. In retrospect I probably would not have gone to the extra expense for the projection system, but I is cool to have a 120 inch TV to watch movies and play video games on!!!
