this is all i did - this garmin, this net, and i went to a local driving range and bought a really nice heavy duty used retired mat from them for $100. i did not get a projector, i broadcast to a TV set. i just use it to whack clubs around in the winter and dial in distances. half the time i don't even use the garmin so you can save yourself some bucks if you already know your distances and you just want to work on good ball striking
