Although the 602 is capable of taking quite good photos it is not really suitable for indoor sports photography.
Unless you have very bright lighting you will find this type of photography very difficult. As with most digicams the inbuilt flash is very limited. This + shutterlag make sports photography a little hit & miss affair. The Minolta A1 would probably fit the bill, especially with it having an inbuilt "image stabaliser" + it's superior handling especially in manual mode,however this costs much more than the 602 & Approx 600-650 £s. Idealy you need to go into a camera shop Preferably with your own memory card and test a few cameras
