You can actually buy on surfline.com for $70 (not sure if you need to be a member), but I prefered to invest 10 bucks more and buy it from target.com, because it seemed it was possible to return it for three months.
You can read all the technical specs on the web, here's my feedback after two days of use:
This is a killer product. Whoever had the idea is going to make major bucks.
It's simple, basic and cheap.
No LCD screen, one little AAA battery (I just bought a pack of 4 rechargeable ones, so I'm good for the eternity).
There's a strep that allows you to put it on you wrist. I also put it on the mast (the videos will be vertical, though), on the boom, on the harness.
Let's see how to operate it.
There's two little buttons on the waterproof housing. You push the one on the front once and it turns the camera on, in the still picture mode. If you want to take a little video, you have to push the same button three more times to set it in the video mode. Unfortunately, that only lasts a few seconds and if you didn't start your video pushing the shutter button on the top, it returns to the still picture mode.
That's the only thing that I would change so far.
If you don't push the shutter at all, the camera turns off by itself after 30 seconds. And that's good, otherwise the little battery would die too soon.
I haven't used it for surfing yet, but I think it's going to be great (specially taking videos of the other surfers).
Shooting while windsurfing is not even mentioned on their website. Operating it is not particularly easy (got to push those buttons while hooked in the harness with one hand on the boom and one on the camera), but a little practice already made me a lot better at it.
The ride is quite bumpy itself, so you better focus on one subject without moving the camera around too much. Another thing I like is that the videos are 12 to 20 seconds long (the video is stops by itself when it reaches 1MB) and that means that no editing will be needed. You go home, download them on the computer, check them out, it you got a good one, you keep it. If not, delete everything.
Anyways, for 80 bucks, I'm having a lot of fun already. And it's only the start.
Here's a little video from yesterday's sessions. It's a mast mounted one, so turn you laptop vertical to the left... Sorry, I don't know how to turn a video 90 degrees... can anybody help?
The video is called: "I get hungry sometimes while sailing..."

a Trestle. Today the main event is off, but they are doing an interesting format with two surfers of the same country surfing together (they have to ride a wave together too). It's quite fun and perfect blogging background activity...
Wow! Taj Burrow just did a huge arial 360 on a small mushy wave!! These guys are incredible...
