Pentax Optio A10 Digital Camera

I have owned many digital cameras, I was excited when I got this one but now very disapointed. After 3 months I had to send it back to the shop. Even after it came back still makes all kinds of weird noises. The first few weeks it took O.K pictures, But my girls are dancers....forget about any action shots with this camera they will all be out of focus and or blurry. I get maybe 3 out of 10 good pictures. My camera before this was better at half the price.
I am stepping up to a better brand. I do a lot of photo shoots,dance competitions and have a new baby on the way. I need good pics. Too bad that 500 is waisted. Oh well my girls will have their own digital camera. Please look around before buying this camera.
I also have yet to see the shake reduction factor work. Maybe I got a defective camera but I have seen much better cameras out on the market.
