The hunt for a CRT monitor - car boot sale or do you have anything in mind?

Been scouring the web and fell down the wormhole of crt gaming. Near zero latency and high refresh rate with almost perfect blacks sounds like something worth experience. It isn't easy though, seems as though it's growing and trying to find a CRT on ebay or FB will set me back £100

Surely there has to be a cheaper way to get 25 year old tech?
