I'd get at least a Hero 3, big change between it and the previous cameras. They all take good video, the newer nicer ones are just easier to run.

I have used a Hero 3 Silver for several years now.

I will caution you this, while the WiFi feature is nice and makes the camera easy to run remotely, it also sucks the battery down quickly. I only use my Wifi to set the camera up now, I start and stop the recording manually by pressing the button. Really helps the battery live longer.
