I almost always try to play on original hardware on an appropriate display (CRT) whenever I can. The deluge of remasters and remakes we've been getting can be nice - but I find a lot of the time that they can be hit or miss. They often feel like they've lost a lot of the magic created when the developers of the era had to work with the limitations of the hardware of the era. Pixel art on those old CRT's vs pixel art…
Finding a good CRT locally has been pretty difficult. I think everyone is caught on the "this is worth gold now" trend.
Shipping them is annoying and expensive, no one wants to lug around heavy ass CRTs and larger ones probably have to ship on pallets.
Small CRTs that are easy to carry will get snatched up quickly, but mostly by retro gamers who have no alternative.
The difficulty of finding CRTs is mostly a logistics problem. Not because they are so valuable that people horde them.
