The A200 is about 3 years old. But if I recall correctly it wasn't the best performing DSLR for its time with a more noisier than average sensor. What lens does the camera come with?
Try sourcing for models like the Canon 450D, Nikon D3000 or Pentax K-x with kit lens. These models perform better with respect to image noise, and are at the least more future proof since Canon, Nikon and Pentax are still continuing on with the DSLR lens production whereas Sony has now seemingly moved on to the mirror-less camera genre.
