I'll agree with the others ... the asking price seems a little high, but may depend on whether the body comes with any accessories, battery grip or flash, for instance, or perhaps which lens, if any, is fitted.
Whilst my K-5 has been superceded by my 24-megapixel bodies for "birding" and astrophotography, as a general-purpose easy-to-use everyday camera the K-5 is comfortably "bulky" in the hand, useful if wearing gloves, and the battery will last all day and then some
Just my tuppence worth ... other bodies are available
