I've been getting things together to build a MAME cab for a while, and just recently ran across an old cabinet that was given to me. I figure I'll use it instead of trying to build the whole thing from scratch. I've looked at options for what to do with the monitor. The monitor has some burn-in from the game it previously ran so I'm not sure if it would be worth fixing (when you turn the cab on, it displays nothing but a vertical line, kinda like the whole image is squished into it, model is a Sampo KGR-1901H). I was also looking at a new monitor, but since this would be a MAME cab, I'd like to have a multisync model if possible, but I'm not sure they're made in 19" varieties. I've found what looks to be a deal on a standard 19" monitor, but don't know about it's quality:

Like I said, I'd like multisync (preferably with VGA) if possible, but it looks like 19" is the limit as far as monitor size goes, which appears to not have much to offer in this regard. I did find a Vision Pro 19" with VGA, but it doesn't appear to support 15KHz.
Other obvious options are either TV tube or standard PC monitor, of course.
