I've thought about getting rid of my CRT TV (a Sharp 25N-S100) a little bit, but I still like using it for when I play older game consoles like NES, Atari 7800, and TI-99/4A. With how my console set up is currently, I have the ability to play most of my retro consoles that are hooked up to my CRT TV on my HD TV through a Retrotink 2x Mini simultaneously thanks to an S-video splitter. My SNES and N64 look great on an HD TV using the Retrotink but my Gamecube (which is the later model with AV multi out only) looks really checkerboard-ie which I assume is due to the 480i signal. But I have a Wii with Component cables so if I want to play Gamecube games on an HD TV I'll just use that, so it's not a huge problem. If you're concerned about space but unsure if you want to abandon CRT TVs, might I suggest maybe getting a smaller CRT like a 9 inch one or maybe a bit bigger?
