I have owned an arcade gun cab, put dual ACT Labs light guns on a MAME cab, and put Ultimarc Aimtrak boards into airsoft 1911s (the only solution that is LCD compatible but needs an LED bar). All work, some work better than others. My preference would be playing a gun game in the dedicated cab for it, then playing gun games using a CRT monitor, then as a far third the LCD option. The CRT guns just do it for me.
