Really depends on your budget. Not sure what they go for over there but here you can pick up wht 70-300 IS for around $400. This lens works great for action shots with enough light (I use the non IS version). The 70-200 F2.8L over here goes for $1200 without IS but is one of the sharpest lenses in the cannon line up, plus the F2.8 allows you to shoot in lower light with a decent shutter speed.
