HPX/HVX is the best bang for your buck camera for skateboarding right now, I shoot on an hvx and it really comes to life when the fisheyes off, the only problem you'll run into is finding wide glass without buying an xtreme I have the opteka 82mm with the flat front element and pushed it out w 2 spacers and it does the job just fine though. plus 200 for that fisheye is a good deal compared to 3000 for an xtreme
