I have decided to go through with building a golf simulator at home. After reading a lot on http://www.golfsimulatorforum.com I went for a pre-used GC2 from Foresight Sports. James at Foresight have been really helpful answering all my questions and provided all the information.
As this still is a budget I went with The Golf Club 2019 as my software. My initial plan was to go with the ProTee system, but I wanted a bit more versatility and the GC2 can be used outside. Jamie at ProTee UK was amazing, answering email both day and night. I ordered TGC 2019 from him along with the impact screen. I choose a screen with HD quality, as I will use the simulator to watch movies and sports as well. TCG has the advantage of having about 150 000 courses to choose from.
I haven’t decided wich projector I will buy, but it will probably be Optoma 1080p darbee or Benq TH671ST. I will keep you all posted as my build progress.
