PhotographyBLOG has reviewed the K2000 and comments:
The new Pentax K-m is another excellent addition to Pentax’s DSLR range. Seamlessly slotting in below the K200D, it offers a simpler and more intuitive layout that will suit beginners better.
The K-m even improves on the more expensive K200D in some areas, notably a faster continuous shooting speed of 3.5 fps, expanded ISO range of 100-3200, and a less cluttered main menu system. Admittedly there are some downgrades, most notably the 5 point AF system which makes it more difficult to track moving subjects, slightly less powerful pop-up flash and the complete lack of any Live View or Digital Preview functionality (the K200D offers the latter).
