2.8 MB JPEG (3872 x 2592)

There is not much difference between these images at all. At close inspection the K200D just pulls a little more detail out of its RAW files than the Nikon D60 but that's certainly not anything you would be able to spot at normal print or on-screen viewing size. The color characteristics are very similar, too.
