The CRT I use the most is a Sony 20" from the 90s. It looks like a million bucks close up. It just doesn't have S-Video I have a Sony 27" wide screen CRT as well which has S-Video in...but it is widescreen.
The TV I always wanted was a Sony 20" for the medical industry which had moduals you could buy for it to add extra tuners, inputs, etc. It came with 4 inputs you could position and display over each other if you wished, like 6 different inputs of which 4 were different video types (at least)...I soooooo wish I had ever been able to afford this TV in the mid 90s when they made it.
That 13" you got there looks pretty sweet though. I just hope it doesn't scrunch the text too bad. In the 80s I had to play on a 9" or 8" portable TV and I know that distorted the text like all hell if it was at the top or bottom of the screen.
For my 13" CRT I have an RF adapter that has an S-Video port. I bought it four or five years ago for no real reason, but now I'm glad I did. One of those shouldn't be too hard to find.
I haven't played my Duo on my new LCD TV yet, but I have played some emulators on it. Some games definitely turn out better than others on the LCD. When the Duo arrives I'll decide whether I'll want to play it on the LCD or my oldschool 13" CRT. I have a feeling I'll be switching back and forth between them. Of course, when I play games on the LCD widescreen I have the screen mode on 4:3 (normal). Stretching the screen on games is unforgivable.
I have to say that Image Fight (MAME) looks fantastic on the LCD. I'm getting totally addicted to that game.
