Fast lens 2.8 Price jumps a lot when you get into this area, best lens for the average photographer that can afford a new lens, would be the 70-200mm f 2.8, it is the professional photographers workhorse lens and can open up a whole new world of what you can shoot. It will also allow you to shoot at 800iso-1600iso in most conditions. But you've already mentioned price range, so I'm assuming that spending $2000+ on just a lens is out of the question. Shooting hockey with a wide can get you great stuff, in close where body checking is involved along the glass, not so good for rec hockey though.
