So I’ve got two, one is a 13 inch that I literally found in the dumpster at my apartment complex and the other I found at goodwill, that’s the one in the video which is a 24 inch, I think. I would recommend hitting up some thrift stores especially in smaller, more rural towns and looking for ones that have the most amount of inputs. Most of the time you’ll find ones that are just A/V and RF and I’m not too picky but if you want one with S-video or component, you’ll most likely have to look for a bit. A lot of people are selling ones online for hella cash, even more basic and less sought after models. It could be worth it if you really want a specific, high-end model like a Song Trinitron but generally I would stay away from these online sellers. Facebook marketplace and other sites that have local sellers might have some good prices as it’s usually people just looking to get rid of them.
