A camera that I really like is the activeon cx. It's a gopro rip off for just under $100 US. It's better than the gopro in that it has an LCD screen so you can see what you're filming, unlike the gopro where it the newest model is the only one with a screen and it's $400. Also, the activeon has a tripod mount built into it so you can put it right onto the tripod without the case. It's also waterproof if it's in the case.
PS: If you do end up getting it, try filming without the case on it whenever possible because the audio quality will be better.
PPS: It has a fisheye effect, but if you set the FOV to narrow in the settings, it won't be as fisheye-y.
