If you are using an ArcadeVGA and going to MAME your machine, I would recommend going with a different monitor entirely. I would consider one of the multisyncs from Billabs, Betson, Happ Controls, or Nieman Displays. I hear that Wells Gardners these days are unrelliable, and it is difficult to run EGA res with an ArcadeVGA, as it usually puts out CGA or VGA depending on the mode. For example, the Billabs BL27CB0P is similarly priced in the range of the D9200, and is far better reliably, and will officially go as high as 1024x768, while at the same time being able to run arcade resoultions natively.
