i am looking for a low cost camera to use for sports and action shots. i am going out to work at a ski resort in the winter and need a camera that can handle the condtions adn take some great shots for my friend to use in a display. i already own a canon 550d which is great but is not the best when using burst mode as the memory is soon used up. any suggestions would be great i dont mind if its an older model as long it produces good quality pics.
