Skytrak (new approx $2k) and GC2 (used $4-5k) both provide very realistic numbers to the sim software. The GC2 is often what Skytrak users gravitate towards when seeking an upgrade. There are plenty of comparisons and discussions on the two on this forum. Keep in mind that both of these measure only ball data... meaning they'll give very realistic shot results for your sim game play, but won't provide any club data if you are looking at using your simulator for swing analysis.

either way, not thinking protee will work... apparently need a camera 6-7feet left or right of ball area, which I dont think will work in this room.
