I just looked up the specs for your camera and it's actually not bad. A 300-400 dollar digicam isn't going to be substantially better.

For moving objects, you need to increase the shutter speed. Your camera will work fine for this situation if you tell it the right thing to do.

If you still have the manual, read through it. Buying a new camera won't solve the problems you are having if you don't learn how to operate it correctly.
