Top Gun II
I wish i would have bought this a long time ago! great company to work with ! I ordered it on Monday night , i received it Thursday !! it was easy to install , (little hard to calibrate but not to bad! ) works great with MAME ! I am using a 20 lcd in my Mame cabinet , and i have to stand away from the machine about 6 feet! If you get one and it is not working right , try to stand back more from the source.
A+ Great product !!!

EMS TopGun II
EMS gets some points for good concept (lightgun that works with all screens, and adjustable laser sight), but unfortunately it just doesn't make the grade due to poor execution... Frankly speaking, I was very disappointed with the TopGun II: The basic calibration with the PS2 lightgun games I tried out were rather hit-or-miss (mostly miss), and its response time for matching what I was aiming at and when the gun's sensors caught up was (IMHO) simply too slow, which is just not good enough for fast-paced lightgun games.
