The Screen itself has a great deal of burn-in and the monitor chassis has seen too many quick 'repairs' for my taste (some of which were likely performed prior to my existence in this world)
While I used to love spending hours trying to perfect CRT monitors back when I got into the Arcade Hobby when I was 15 - I'm now 25, married, and finishing College so I'm taking the lazy way out and would prefer the simplicity of a monitor meant for a PC.
Though I know using an original CRT Arcade monitor is technically possible with a PC, I want to make this project as plug-n-play as possible.
Do I know that TwoBits makes an LCD? Yes - I'm just interested in their mounting brackets rather than their $300-400 monitors

Have I heard about 8Liners and Wei Yea Monitor chassis? Yes - I would absolutely go those routes if I were interested in continuing to use the CRT.
At this point, should I simply take a measuring tape to the original CRT in my Galaga and see if it's closer to a 20' or 21' inch monitor across? The only thing I'm worried about is mounting the 19' up only to have it look too small.
I just figured someone here on the forums has possibly retro-fitted a similar style Midway Cabinet like Ms. Pac or Galaga for a MAME project and had some advice on the proper monitor size.
