Cheap Sport camera?

Hey all. I'm pretty much new to this camera thing, I'm really into mountain biking and like to take pictures when out riding. I'm currently using a nikon coolpix 3200, and really like it, I find I don't really have to pan when using sport mode as it tends to capture everything relatively quickly, for example I took this with it last year http://photo.pinkbike.com/photo/920/pbpic920269.jpg . But it's a bit dated now and I'd like a new camera for the summer, I'm quite interested in this http://tinyurl.com/2guajn , it has ISO 1600 which takes pretty decent action pics? And its a nice price for a student. However someone has suggested this http://tinyurl.com/3clasq as the f 2.8 lens will take really nice clear pictures, however I'm not pleased about having to spend that much, so basically I'm looking for a camera that will take clear crisp action pictures for not too much money, I've got a budget of £100-180 (would rather keep it under £150). Will the fuji take decent action shots or can anyone suggest a different camera, for under £150 (please). :)

There are tradeoffs with any camera, but I haven't kept up with all that is available these days. A lens with an f2.8 maximum aperture will help in lower light situations so that you can keep the shutter speed higher at the same ISO speed. The lower number, the bigger the maximum aperture - "faster" as it's known.
