Replying to Wide Angle or Fisheye

Ok, so i shoot with a DVX100p, and i have a budget of 200$ So if i want quality glass then ill have to buy used which is no problem at all, but i can either get a 0.45x 16x9inc fisheye for 200$ shipped or a 0.6x century optics wide angle for 150$ shipped both are pretty minty, but im not sure which one i should get and if this helps at all, i shoot 60% skiing and snowboarding 20% skateboarding, 10% bmxing, and 10% fruitbooting, i also sometimes shoot short films but that doesnt matter...
