From the review that calls the K20D "Highly Recommended":
"In short, the K20D is a great stab at making a photographers' camera - a camera for people who love taking images, are happy to invest in lenses (perhaps the primes that can make the most of those 14.6 million pixels), but aren't going to be recouping the cost of their equipment through regularly selling images. It offers a very pleasant, near pro-level, photographic experience at a reasonable cost and in a body that feels solid, well built and as if it was designed by someone who used one themselves.
Because the K20D offers so much that the enthusiast photographer would enjoy, it would be churlish to let the sensor-based flaws, which have little impact in real-world shooting, prevent us giving the camera our highest award. This isn't to say it's a faultless camera or one that's suited to everybody but one with only minor drawbacks that should only dissuade a small number of potential buyers."
