- Pick up one of the dozen CRTs at the thrift store down the street?
- Settle for upscaling with composite, and s-video and RGB where possible?
- Mod everything for RGB and find a Framemeister?
- Sell everything that can't output HDMI and replace them with clones? Retrons/Analogues/wait for the Polymega?
You definitely have all of the options well researched. I too have a CRT in my office and
three four backups in my garage. Even so, a couple of those are lower quality (no S-Video) so I should be actively watching my local thrift stores for better replacements.
I am a bit curious about the RGB mods and Framemeister. If I were an active live streamer, it would almost be a requirement. But to do it is such an investment. Plus I'm the type who would rather keep a console 'stock', so I would have to have duplicate purchases for every mod.
