Best Monitor for Light Gun Games

[runawayabc123]

I'm looking to build/run a light gun cab and a 4 player cab both are late 80s/early 90s games.  I want them both to use the same monitor as light guns will ALWAYS need a CRT and the 4 player cab will actively carry my backup monitor.  (I currently have an operation thunderbolt cab with a Hantrex in it.  It could be upgraded to the same as another backup for my light gun cab.) 

I am working on building a switching harness for both (And the operation thunderbolt so I can run it with Zombie Raid).  So, my needs are similar to MAME, in that I will be running many different games on 1 monitor.  However, my generations of games are much closer together.  If resonable, the 4 player cab may also run MAME. 

So, what monitor will work best for both of these cabs? 
Currently I have a ton of PCBs (light gun and 2-4 player games), a couple are
Leathal Enforcers I+II
Area 51
Invasion
Turkey Hunter
Police Trainer
CarnEvil

TMNT
Simpsons
Sunset Riders
Bad Dudes

I am currently running all of these and more on my TV through a converter board.  (The only exception being Carnevil doesn't want to work on it or the board is bad.) 

I read through how the tri-mode monitors are gone (which are best for mame).  So, I am looking to get a pair of new ones for years of light gun game playing. 

Thanks!

Also, if anyone can point out the correct 15 pin connector and contacts for the monitor (and the power one two so I don't have to buy a power cable), the would be great!
