wink It's a really nice camera that'll use all your old manual Pentax lenses. It's got image stabilization in the body too ~ great choice!
I/S on the body SOUNDS like a good idea, but it's only marginally helpful, especially if you use telephoto lenses. The effectiveness of body IS is only a fraction of lens IS because most camera shake comes from the lens, not the body. The body moves and the lens vibrates--if the body has IS and not the lens, the image can still get warped.
However, I find that once you learn how to properly expose your photos image stabilization isn't that important. I have no problem with camera shake even outdoors, in sports arenas, etc. Unless you're just really clumsy... just learn how to use light.
