I'm currently redoing my first arcade machine. I don't have the funds to add light guns at the moment, but I'd like to at some point in the future. Being that I have to remount a new monitor and make a new bezel and all that, I think it would make sense for me to think ahead and mount an AimTrak light sensor bar thing at the same time. Now due to the lack of funds like I mentioned... Is there a way to purchase just a light sensor? That say I can mount it and just hook it up later. Please let me know! I didn't see a way on the Ultimarc website but maybe one of you has an extra one or something?
