I record on my cell phone. Whether I had a channel or not, I would have a phone (currently Huawei Nova 3i, used to be Samsung J5). I stick with medium priced phones. Decent enough cameras, especially just for YT. I did buy a nice large tripod on a visit to the US (only a $40 tripod). Also, I built my own green screen with lights, for under $20. I do use a Chinese knock-off Gorilla pod ($3), and no name lapel mic ($20). My most expensive extra piece of gear is my gimbal. It was $100 and I bought it with a YouTube check.
So... yeah... pretty cheap ha ha
