LOL WAT? I could go to every store in my entire city and there would be ZERO standard def TVs for purchase. 720p? Sure, lots of those but that's still HD.
Gotta agree with this. Even a year and a half ago, I spent months trying to find a SD TV (or at least 480p EDTV) because I was making a setup for my older consoles. But even the smallest TVs were at least 720p and the only SD ones I found were ridiculous expensive ones on eBay that required local pickup anyways. I can't see ever finding these for sale anymore unless it's at a garage sale or something and the one I acquired was because a coworker didn't want it anymore.
I would love a small LCD with 480p resolution for my classic console setup, but 720p+ are what sell so I doubt I will be able to find one.
