TV Light Gun Questions

[greaser]

I'd like to someday purchase a light gun to use in my cab which utilizes a 27" Sharp TV as the monitor. Which gun performs the best with a TV and also do any of the guns support games such as operation wolf, revolution x, and terminator 2? All of these games used a machine gun which didn't require pressing the trigger for each shot. In other words can any of the tv compatible light guns work so that you can just hold the trigger down instead of pressing it for each single shot? I also realize that all 3 of the above mentioned games didn't actually use a light gun but a special joystick shaped like a gun. As always any advice is appreciated.
