using arcade monitors is a lot of work, unless you can afford to find and ship a fully working one or live in a place where lots of working monitors are plentiful.
otherwise be prepared to spend a lot of time digging for parts, jumping on opportunities to get parts at a moment's notice, drive a ways to get monitors, and learn how to diagnose and fix them.
I have 5 in various stages of working to not working and its been a very interesting challenge so far but pretty satisfying to bring them back from the dead. your milage may vary.
having said that I'm very new to all the monitor stuff and still working my way to the top of the learning curve. but I dont' reccomend messing with them unless you really want to. the amount of stuff you have to learn can be daunting.
