I currently use a PlaySport, which I am pleased with the quality of. 720 60 FPS is great for pulling stills and reviewing video in slow motion. 1080 seems like asking a lot from the little camera in this but the quality is good. Battery life is poor at maybe 2 hours, but you can get batteries cheap online. For $150 I can't complain.

It just sucks that people aren't into taking vids all the time, it's more fun to sit and relax and be in the moment than enjoy it later on video. I prefer to get every run everyone makes (shotgun theory, great shots through pure volume) and sift through the video, because you never know what you'll get. Trakker is one option, Wakejac also looked similar and pretty decent. Both are pricey, and all cam mounts seem similarly priced.

I'm actually thinking about making one of these tracking mounts myself. Doesn't seem too difficult. I could probably make one for $20-$30 or so if I went real cheap. I run an expended pylon with a swiveling bushing the rope goes over... Thinking one of two ways to do it, one would be get a thin clamp and clamp it right to the swiveling part, attach the clamp to some all thread with a 90* bend up, put a nut on it and attach camera on top.

The other way, would be a copy of the Trakker. Clamp goes to pylon with some flat stock bent to a U shape having a plate above the pylon. Have a swiveling part on top which could b done one of two ways. Cheapest would be a piece of flat plate with a greased bushing (either metal or nylon) between the plates, lightly preloaded, and have a wire coming out the front to hold the rope. Alternatively the swivel could be mounted on some small bearings. I could probably make some from an old bike tripple tree I have, so it would ride on roller bearings. Alternatively I could use a straight ball bearing pressed/welded to the U plate and a rod pressed/welded to a shaft coming off the bottom of the top plate.

So I think there are some cheap home made options that wouldn't be too difficult to make. If I ever get bored and find some creativity I might try to make one.
