It has been very tempting. The main reasons that I don't are (1) TVs are
cheaper, (2) modern arcade cabs are mostly 25", and (3) I want to buy a
monitor bezel/shroud, and those are made for 25" monitors.

Haha, 26 years and going strong. The wife has bought into my "retro"
theme for the living room. No way she'd go for 2 of them, though.

I don't follow you on this one. Golden age games come in vertical and
horizontal. How does one 19" monitor work for you?

I don't understand. How can ver and horiz games be sized the same?
Either the (1) aspect ration must change, which would cuase the game to
look too tall & skinny or too short & fat, or (2) the aspect ratio stays
the same but the game is smaller on the screen, which leaves black
areas. How does hwstretch compensate for that? And what does the service
menu have to do with it? Sorry, I'm a real noob.

Same question again. How does streching overcome the basic problem of
the game's aspect ratio without making it too short/fat/tall/skinny?
