Happ sells a 19" CGA monitor made by Tovis in their "Vision Master" line. I've seen one in person, and the picture is great. Has good controls. Haven't had to perform any "surgery" on it, so I can't comment on design, but of course it also hasn't broken

Their price is $183 for shelf mount or $193.85 for a universal (not bad at all, really, for a brand new monitor), or you may be able to get a better deal through one of the Happ distributor/representatives here on the forums.
Not sure if that's exactly what you require (that is likely a 19" viewable), so check dimensions.
