Yeah, I asked one of you guys on youtube about non-HD LCD screens the other day (I have no idea which one of you runs the channel).
I was kinda bullheaded and got one anyway.
I probably won't ever play any light-gun games (not my cup of tea, sorry), so light-gun compatibility doesn't concern me.
The two criteria I was mostly looking for was minimal lag, and smallest footprint; the reason for wanting minimal lag is obvious, but for the footprint I'm pretty strapped for space and don't have a good place to put even a small CRT. I'm probably pretty lucky with the one that I managed to pick up (it was a Sharp Aquos LC13S1US, specifically): there isn't any easily discernible lag on it, and I couldn't ask for a better footprint; while non-HD streams may never look as sharp on an LCD as a CRT, for 60 bucks, I'd have to say I'm pretty happy with it.
