Summary: I sent my camera in for repair after maybe 500 shots. Shortly after, I received and email saying that the repair wasn't going to be covered by the warranty. Pentax concluded that I improperly used the batteries (leaving them in the camera for about a month). I contested that something was wrong with the camera when I purchased it - where a fresh set of batteries would last maybe 3 or 4 hours at best and be burning hot when I would replace them.
Update: went dead in the water after 16 months of use. Avoid.

Summary: Update: The original 5-star review I wrote in November 2010 follows below. The revised 1-star review is based on a sudden and total failure of this camera after just 16 months of operation (during which I used it to take around 6500 images). It simply stopped working while I was taking pictures on a clear, calm spring day.
