There are plenty of options. Ultimarc sells the AIM-Trac which you can install into anything that looks like a gun and has a trigger....(at least I think thats how it works...) There are ACT Labs guns you can use, there is the TopGun as well. I bought a Top gun because I have a LCD in my Cab, but I never installed it into my cab, i used it with my PS2 a little to play Time Crisis. I have heard a lot of people say they do not like the top gun because you have to stand far away from the screen. I know people have also tried fixing this issue with Wide angle lenses. One of the main reasons I got the Top Gun was because I could use it on any screen, and it has slider recoil when a shot is fired.
