Replying to What camera for filming myself

This is probably a dumb question but what are some good cheaper cameras for just filming an entire session on a rail? I don't always have people to film me and sometimes i just want to film an entire session on a tripod or whatever but editing out a 10 minute clip every time I land the trick im going for is a pain so I was looking at the gopro hero 9 for the hindsight feature but it seems kind of pricey and I'm just wondering about other cheaper cameras that are similar just for filming an entire session and getting new clips on a rail without having to convince my friends to film me for an hour while i try elusives over and over again
