By my way of looking at it, the Pentax K-X looks like it's definitely the better camera at the beginner level, compared against the Nikon D3000--the Pentax has several key areas where it is better--it has in-body stabilization, shoots pretty decent HD video, has better low-light and high-ISO performance, has a wider sensor dynamic range, better color depth, and is overall, a better "imager" than the Nikon D3000. The Pentax K-X is also a very low-cost camera,and it's my understanding that its 4.7 frames per second shooting rate is the fastest of any entry-level camera offered by any brand. It's also a class leader at ISO 800 and higher settings...so for a guy who already has some Pentax lenses, it seems like the low cost of the K-X brings with it multiple class-leading advantages.
