"For older analog cathode ray tube (CRT) technology, display lag is extremely low, due to the nature of the technology, which does not have the ability to store image data before display." - https://en.wikipedia.org/wiki/Display_lag

It's cool knowing there's like NO latency, I would rather use a CRT. Also check sites like EBay, Craigslist, and LetGo. I've found many o' plenty of CRTs that people want to get rid of for free that way.
