If you want to replace a monitor with burn, now is a good time to do it.  The LCDs don't look right, but you know that and for $250 Wells Gardner has a new drop in replacement.  Kinda hard to argue with the simplicity and you could always put another CRT back in later if you decided to.

I replaced the CRT with an LCD in my MAME cab last month.  Bugged me for 5 minutes, now I think it's fine.
