One thing you may want to keep in mind is that games on the same hardware will have the same monitor outputs. So if your running a CPS1 SF2, then all CPS1 shooters will be displayed perfectly on your monitor. Likewise if your playing a version of Super Street Fighter II on CPS2, then other CPS2 games will have the same monitor settings. I don't have many CPS1 games (just mercs) but I believe they have the same (or similar) monitor dimensions as CPS2 games.
I'm just mentioning this because lots of USA cabs have the monitor controls way in the back and they really aren't worth adjusting every time if you plan on switching games a lot.
I'll have to second Progear. Game is top notch. Also, if you haven't, upgrade to Super Street Fighter 2 Turbo.
