The Kr is a very good upper entry level camera. Pentax introduced the Kx several years back and it was touted as being one of the best entry level cameras. Folks are still buying the Kx today. The Kr was built off the Kx platform and added some things that weren't in the Kx, ie, visible focus points and a few others. I don't think you will be disappointed with the camera. Saying that, I would recommend that you start studying about photography. There is an educational component to learning how to use a DSLR. Yes, you can put it on automatic and use it as a P & S, but why? There are some online tutorials and there is a book by Bryan Peterson, Understanding Exposure, that is very good at explaining the photographic triangle of ISO, aperture and shutter speed. Purchasing the camera is only the first step. Have you thought about what lenses you will want? Most everyone starts with the 18-55 kit lens and maybe a kit zoom lens. When I say kit, I am referring to a basic consumer lens that will work well in normal conditions. There are lenses out there called all-in-one's that have a larger range of zoom that don't call for changing lenses (18-135mm, 18-200mm, 18-250mm). These lenses give you convenience, but there is a trade off in that they struggle in lowlight conditions. Sometimes folks will forgo the kit lens and purchase a camera body with an all-in-one.
There are many options out there and all the manufacturers produce quality products. I have used a Pentax slr and dslr for thirty years and am not disappointed in their cameras. My DSLR's are now 4-5 years old in terms of technology and every time I think of upgrading they produce an image that blows me away! I am a happy Pentaxian. Good luck with your research and if you put a little effort into learning about your camera, you won't be disappointed.
