Does anybody have one of these camera's? I do, and I love it!

I got one for Christmas last year and I have used it for everything.
Underwater pictures in our pool and in the ocean, Family portrait's, action shots... It has a wide-angle feature, 10-shots per second burst.

It records in 1080p HD video/audio. Has a slo-mo feature on play-back of 29 frames per second. I use if for recording golf swings, zip lines, obstacle courses, grappling/jiu-jitsu mechanic's... you name it.

I recommend the HD Hero 2. With the LCD bacpac (optional screen just like any other digital camera) and WiFi reciever W/ remote (can control up to 50 camera's at once, also can provide a real-time view from the camera to a smart phone or tablet)
There are other accessories you can buy, such as mounts, longer life batteries, charging devices.... But you can't go wrong, trust me.

How is the audio on it?
I play music a lot and I'd like to find some kind of camera to record stuff for youtube - but most of the stuff I find is pretty cheap on the audio side.

When the water-proof housing in on the camera... the audio is very low. Clear, but low.
When the camera is out of the housing, it's very clear. I'll PM you Mr. Zaga Fan some video's I shot with it and let you see what you think
