I can chime in. I have one, sitting in my Tekken 5 cab now, and have dealt with several in Ghost Squad cabs.
1st, they are VGA only, so if you are looking for tri-sync capabilities, you're in the wrong place.
2nd, they are known for having mediocre tubes, and some common geometry issues. My tekken cab has a small bump almost like a pincusion issue, but not, along the bottom edge. Capped it, adjusted it, wont come out. It's not major, and is totally playable, and my tube is fortunately in very good shape. The Ghost Squad's I've worked with tend to lose color brightness, and its the tube...not the chassis. Saw one of my co-workers have to Zap a tube 6 times to get the colors to come back fully...which I don't recommend, but it was that or toss the tube, and that wasnt gonna happen.
3rd, I believe there is a weiya or rodotron chassis that can give them tri-sync abilities, but you'd have to get a reply from like giz10p, or videotronics, cause i've never had the ability to come across one.
4th, as long as the tube isnt burnt, and the colors are bright, it's a solid monitor with the true flat tube the AWSD needs to fit it's bezel, and they can look quite nice. The chassis are well spaced, and are way easier than Wei-ya's to cap and work on.
My original trisync died when I accidently broke the neck on it...so I've been running a weiya 2929d in my cab for a good while...there are lots of easy ways to go with vga (raspi/pandora/x360/mame/etc), so the cab is still perfectly useable without trisync. If I ever lost the monitor though, I'd pull my es31 and drop it into my AWSD in a heartbeat.
If you do drop it in though, when you pull the original monitor....see if you cant get the chassis off to giz or someone, as the weiya's ARE repairable, and as long as your tube isnt toast, you should be able to get your trisync weiya up and running again, for a reasonable fee.
Best of luck, hope this helps....if you need more, PM me...I will help any way I can.
