My girlfriend planned a vacation to NY and, among other things, we are going to be doing a bobsled experience. I'm super excited yet nervous for this one. But it got me thinking that I would like to take a cheap action cam along for the trip. I want something that can record in 4K at a high framerate, but I also don't want to worry too much about losing it. It's something I'll probably use for this trip and not again for another year or so and for that reason I don't want to spend too much. I also don't want to deal with overheating cameras (looking at you GoPro). Thoughts? What's the hot new budget action cam?
